An object has a mass of 75 kg and an acceleration of 15 m/s. what force is applied to that object

1125 N

Explanation:

An object has a mass of 75 kg,

and an acceleration of 15m/s²

According to Newton's second law of motion, F = MA (where 'f' is the applied force, 'm' is the mass of the object and 'a' is the acceleration of the object)

Applied force (F) = 75 kg × 15 m/s² = 1125N

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
