An object starts from rest and accelerates at a rate of . If the object has a mass of 10kg, what is its kinetic energy after three seconds?

An object has a mass of 5kg and has a position described by the given function:

What is the object's kinetic energy after two seconds?

A train car with a mass of 2400 kg starts from rest at the top of a 150 meter-high hill. What will its velocity be when it reaches the bottom of the hill, assuming that the bottom of the hill is the reference level.

A 120kg box has a kinetic energy of 2300J. What is its velocity?
