How far does a 1.58-kg stone with the kinetic energy of 3.11 J go in 1.86 s if it is moving in a straight line?
1 answer
It can only go in a stright line if it is thrown straight up or down, or if there is no gravity. You need to know which it is. The kinetic energy tells you the initial speed. If there is no gravity, it will maintain that speed.
