what effect is seen in the kinetic energy of a moving stone, if its mass is decreased by 2 times and velocity increases by 4 times? also show by calculation.​

A12-kg bag of groceries is tossed onto a table at 4.0 m/s and slides to a stop in 2.2 s . modify the equation fδt=δ (mv) to find the force of friction.

Acar travels 40m in 8 seconds find the car speed

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
