22. An object has a mass of 120 kg on the moon. What is the force of gravity acting on the object on the
moon?
A. 1,176 N
B. 196 N
C. 20 N
D. 12.24 N

An object has a mass of 120 kg on the Moon. The force of gravity acting on the object on the Moon is 196 N. Solution: Weight = (mass) x (acceleration of gravity) . Acceleration of gravity on the moon is 1.622 m/s² (rounded) . Weight of the object = (120 kg) x (1.622 m/s²) = 196 Newtons.

An object has a mass of 120 kg on the Moon. The force of gravity acting on the object on the Moon is 196 N.

Solution:

Weight = (mass) x (acceleration of gravity) .

Acceleration of gravity on the moon is 1.622 m/s² (rounded) .

Weight of the object = (120 kg) x (1.622 m/s²) = 196 Newtons.

Solution:

Weight = (mass) x (acceleration of gravity) .

Acceleration of gravity on the moon is 1.622 m/s² (rounded) .

Weight of the object = (120 kg) x (1.622 m/s²) = 196 Newtons.

If a stone with an original velocity of 0 is falling from a ledge and takes 8 seconds to hit the ground, the final velocity of the stone is 78.4 m/s.

Solution: v = gt v = (9.81 m/s^2)(8s) v = 78.4 m/s.

Solution: v = gt v = (9.81 m/s^2)(8s) v = 78.4 m/s.

A car with a mass of 1,200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second. The centripetal force on the car is 6,000 newtons. The radius of the curve is 80 meter.

Solution: cf = mv^2/r, 6000 = 1200*400/r

r = 80 meters.

Solution: cf = mv^2/r, 6000 = 1200*400/r

r = 80 meters.

An object has a mass of 120 kg on the moon. the force of gravity acting on the object on the moon is 196N.

Force = mass *acc, Force = 120 * 9.8 /6 = 196N.

Force = mass *acc, Force = 120 * 9.8 /6 = 196N.
