If a 75 kg person and a 200 kg crate were launched out of a plane at the same time which one would hit the ground first?
Impossible to say for certain as it would depend on air resistance. Assuming the person is conscious, he could choose to assume a diving position (in which case he'd probably fall faster than the crate since he'd be more streamlined) or a "belly flop" position (in which case he'd probably fall slower than the crate since he'd be less streamlined). If this were done in a vacuum they'd hit at the same time. Then again, if it were done in a vacuum, a plane is going to have a really hard time flying.
What else can I help you with?
How does gravity affect a ball launched from a catapult?
Gravity affects a ball launched from a catapult by pulling it downward towards the Earth, influencing its trajectory and causing it to follow a curved path. The force of gravity acts as a constant acceleration on the ball, pulling it towards the ground as it travels through the air after being launched.
If a 75 kg person and a 200 kg crate were launched out of a plane at the same time which one would reach terminal velocity first?
As Galileo demonstrated, acceleration is independent of mass, therefore, they would reach terminal velocity at the same time. This is, of course, ignoring air friction.
If a crate weighing 508 N is resting on a plane inclined 26degrees above the horizontal if acceleration is 4.29 then how fast will the crate be moving after 6 seconds?
To determine the speed of the crate after 6 seconds, we first need to calculate the net force acting on the crate on the inclined plane. This can be done by resolving the weight of the crate into components parallel and perpendicular to the plane. Then, using Newton's second law, F = ma, where F is the net force, m is the mass of the crate, and a is the acceleration, we can find the acceleration down the incline. After finding this acceleration, we can use the kinematic equation v = u + at to calculate the final speed of the crate after 6 seconds, where v is the final velocity, u is the initial velocity (assumed to be 0), a is the acceleration, and t is the time.
What was the name of the first rocket to bring an animal to space?
First Animal in SpaceThe first animals intentionally sent into space were fruit flies, which traveled along with corn seeds aboard a U.S.-launched V2 rocket in mid July, 1946. The purpose of the experiment was to explore the effects of radiation exposure at high altitudes. Some further V2 missions carried biological samples, including moss. A rhesus monkey called Albert became the first monkey launched on June 11, 1948; also on board a US-launched V2 rocket. Albert suffocated during the flight.The generally accepted definition of the boundary between earth's atmosphere and "space" is 100 km (62 mi.) altitude, known as the Karman line. Thus, the first "Albert," who flew on a V2 on June 11, 1948 did not fly into space, reaching an altitude of 63 km (38 mi.). Albert II flew into space on June 14, 1949, reaching an altitude of 134 km (83 mi.). Also, it is not clear from commonly available sources whether the 1946 fruit flies reached space or not.Albert II in a U.S. launched V2 became the first monkey in space on June 14, 1949 (after the failure of the original Albert's mission). He was killed on impact after a parachute failure on his return to Earth.Numerous monkeys of several species were flown by the U.S. in the 1950s and 60s.Laika, a Russian dog, and the first animal in orbit, was launched on 3 November 1957 and died a few hours later from stress and overheating resulting from a failure of the temperature control system.At least 10 more dogs were launched into space and on sub-orbital flights by the Soviets until April 12, 1961, when Yuri Gagarin became the first human in space. Since those first historic launches, many monkeys, chimpanzees, rats, mice, frogs, spiders, cats, gorillas and even a tortoise were launched into space.Other contributors have said:The first rocket ever sent to space probably carried bacteria or some other accidental passenger. But the first animals ever intentionally sent into space were fruit flies launched aboard a V2 rocket in 1947. US scientists were studying the effects of radiation at high altitude.A rhesus monkey called Albert 1 became the first monkey launched into space on June 11, 1948; also on board a US-launched V2 rocket. These were just suborbital flights, though. The first animal to actually go into orbit was the dog Laika, launched on board the Soviet Sputnik 2 spacecraft on November 3, 1957. Unfortunately, Laika died during the flight. At least 10 more dogs were launched into space and on sub-orbital flights by the Soviets until April 12, 1961, when Yuri Gagarin became the first human in space. Since those first historic launches, many monkeys, chimpanzees, rats, mice, frogs, spiders, cats, gorillas and even a tortoise were launched into space.
Who discovered the concept of weight?
The concept of weight was likely discovered by ancient civilizations through observations of objects falling to the ground. The concept was later formalized by scientists such as Galileo and Isaac Newton.
If a 75kg person and a 200kg crate are each parachuted to earth from a plane which will hit the the ground first?
Provided that the parachute has the same surface area for both of the parachutist's, the 200kg man will hit the ground first due to the extra weight from the heavier man.
Who was the first person launched into space?
Uri gagarin
Who was the first person to be launched in to space?
Yuri Gagarin,
A 75 kg person and a 200 kg crate are each parachuted to earth from a plane which will hit the ground first?
With parachutes and air resistance in the mix, the heavier object probably hits the ground first. If they were simply released from altitude and fell freely, without parachutes or air resistance, then they hit the ground at the same time, no matter how their masses or weights compare.
Which one will hit the ground first when you have two cannonballs and one is dropped while the other is launched?
They both hit the ground at the same time.
What is the name of the person who launched the first satellite?
The Russians launched the first successful satellite. The leader of the project was lead by Sergey Pavlovich Korolyov as head Soviet rocket engineer.
What were the dates of the first person and first American in space?
The first person in space was Yuri Gagarin from the USSR. He launched on April 12, 1961 aboard the Vostok 1. The first American in space was Alan Sheppard, who was launched into space aboard Mercury 3 on May 5, 1961.
What was the name of the spacecfrat that launched the first person into outer space?
The space program that launched the first person into outer space was the Soviet program called Vostok. Yuri Gagarin was the first human to go into space aboard Vostok 1 on April 12, 1961.
When was Facebook first launched?
Facebook was first launched in 2006
