Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
How many miles an object take to escape from earths gravitational pull?
To fully escape Earth's gravitational pull, an object would need to reach a speed of about 25,000 mph or approximately 40,000 km/h. This is known as the escape velocity and is the minimum speed required for an object to break free from Earth's gravity. The distance an object would need to travel to achieve this speed would depend on various factors such as altitude, initial velocity, and atmospheric conditions.
How was Pioneer 10 able to escape the solar system with an initial speed less than escape speed?
Pioneer 10 was able to escape the solar system despite an initial speed less than the escape velocity due to a combination of gravitational assists and its trajectory. After its launch in 1972, it performed a close flyby of Jupiter in 1973, where the planet's massive gravity provided a significant boost to its speed. This gravitational slingshot effect increased Pioneer 10's velocity enough to allow it to surpass the solar system's escape velocity and continue its journey into interstellar space.
How much minimum torque is required by a turbine to generate Electricity?
initial torque to overcome the friction in generator and then to keep constant speed of stator within the generator. Minimum 50NM
A ball rolling down an incline has its minimum speed?
The minimum speed of a ball rolling down an incline occurs when all its initial potential energy at the top of the incline is converted to kinetic energy at the bottom, without any loss to friction or other factors. This minimum speed can be calculated using the principle of conservation of energy.
What is initial speed?
initial speed means first
What is escape volocity?
Escape velocity is the minimum speed that an object must reach to break free from the gravitational pull of a celestial body. This velocity allows the object to overcome the body's gravitational force and enter into space. The specific value of escape velocity depends on the mass and radius of the celestial body.
How do you work out the initial speed?
To calculate initial speed (also known as initial velocity), use the following formula: initial speed = (final speed - acceleration*time). You will need to know the final speed, acceleration, and time to calculate the initial speed accurately.
What is the definition of initial speed?
Initial speed is the original, beginning speed of an object.
Do you need a speed of Mach 1 to escape the Earth's gravity?
No, the escape speed is actually much higher. It is about 11.2 km/s. Note that you do not need to reach this if you are in a powered spacecraft. This speed is only valid if you get this initial speed at Earth's surface and fly up, keeping your engines off. (also it ignores air resistance). Mach 1 is equal to the speed of sounds, about 340 m/s. Although this number varies greatly with humidity, air pressure and temperature.
At what point in its trajectory does a batted baseball have its minimum speed?
A batted baseball has its minimum speed at the highest point of its trajectory. This is where the kinetic energy from the initial hit has been mostly converted into potential energy due to gravity pulling the ball back down.
What is the name for the speed a rocket must reach to escape the earth's gravity?
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
