What is the magnitude of the force the car excerts on the trailer if the car that is towing a trailer is accelerating on a level road?
acceleration x Mass of trailer = force.
How does weight change at mean sea level and Mt. Helens?
Your weight(force due to gravity) equals your mass times the acceleration due to gravity(g). g=G*(Mass of Earth)/(r^2) So (force@helens)/(force@sea level)= g(@helens)/g(@sea level)= [(radius of earth)/(radius of the earth+height of helens)]^2 radius of earth = 6378.1 km Altitude of mt helens = 2.55 km Your mass cancels out because it is equal regardless of gravity. So your weight at mt helens is equal to 99.92% of your weight at sea level. Hope that helps
What is the label for pressure?
Force has the symbol F (don't forget the italic) Electrical force is Fe Gravitational force is Fg
The value of acceleration due gravity at mountain?
Technically, the acceleration due to gravity is inversely proportional to the square of the distance from the center of the earth. That means that the farther from the earth's center you are, the smaller the acceleration due to gravity is. So gravitational acceleration is smaller on a mountain-top or in an airplane. Let's do a little calculation to get an idea of how much it changes. Let's figure out the acceleration of gravity inside an airplane at 35,000 ft above sea level: -- We know what it is at sea level on the equator: 9.78 meters per second2. That's when our distance from the center of the earth is equal to the earth's radius = 3,963 miles. -- When we're at 35,000 ft, we're farther from the center of the earth. 35,000 ft = (35,000 / 5280) = 6.63 miles. So our total distance from the center of the earth is (3,963 + 6.63) = 3,969.63 miles. -- The acceleration (and force) of gravity is inversely proportional to the square of this distance, so the new number is 9.78 times (3963 / 3969.63)2 = 9.78 x (0.9983298)2 = 9.78 x (0.996662) = 9.74736 m/s2 We have discovered that the acceleration due to gravity ... and the weight of every passenger in the airplane ... has become 0.33 percent smaller since they left the ground, because the distance from the center of the earth has increased. If you normally weigh 250 pounds on your bathroom scale, then at 35,000 ft, you weigh only 249.17 pounds.
How much is 20 kilogram in pounds?
20 kilograms = 44.09 pounds.the formula to convert kg to pounds:20 kg*2.2046 lbs1 kg=44.09245244 lbsKilograms cannot be actually converted directly to pounds, without reference to gravity or other force of acceleration. Kilograms measure mass, while pounds measure weight. It is typical, however, to speak of the weight of a mass under the force of gravity on earth (at sea level, etc.), which is approximately 2.2046 pounds per 1 kilogram. This means that a 20-kilogram mass on Earth at sea level weighs approximately 44.09 pounds.
What two things affect the level of an object acceleration?
The force acting upon the object as well as the mass of the object. Both will affect the acceleration of the object.
What is the magnitude of the force the car excerts on the trailer if the car that is towing a trailer is accelerating on a level road?
acceleration x Mass of trailer = force.
What force is needed to give a 6000 kilogram truck an acceleration of 2.2 meters per second squared over a level road?
fROM nEWTON'S 2ND LAW, F = ma where m = mass and a = acceleration F = 6000 x 2.2 = 13,200 kg-m/sec2 = 13200 Newtons
What is the net force acting on a car cruising at a constant velocity of 70 kmh on a level road?
If the velocity is constant (no acceleration), the net force is zero.
What force of 2.0 kg mass and acceleration of 5.0 MS's on a level surface what is the force applied to the mass?
Force = Mass x Acceleration Force = 5 x 2 Force = 10N (Newtons)
What supplies the needed centripetal force in a car turning a corner on a level road?
friction
What is the planet earth's gravitational force?
This can be measured by the acceleration due to gravity at the surface. Earth's surface gravitational acceleration is about 9.8 m/s2
A force of 20 N gives a ball an acceleration of 4.0 ms on a level frictionless surface what is the mass of the ball?
F=mam=F/am=20/4.0m=5Kg
A car located on a level highway has a mass of 400 kg. The friction force opposing the motion of the car is 750 N. What acceleration will a force of 2250 N produce on the car?
Give me the exact answer
A box is dragged without acceleration in a straight line across a level surface by a force of 13N what is the frictional force between the box and the surface?
13N. if a=0, the sum of all forces is zero so the force of friction is equal and opposite to the dragging force.
An unknown force pushes an automobile mass 1700 kg The automobile is on level ground and accelerates at a rate of 3 meters per square second What is the magnitude of the force?
Use Newton's Second Law: force = mass x acceleration.
