An object has a mass of #9 kg#. The object's kinetic energy uniformly changes from #135 KJ# to # 45 KJ# over #t in [0, 4 s]#. What is the average speed of the object?
The given data:
Kinetic Energy initial
Kinetic Energy final
Compute for initial velocity
Compute for final velocity
Solve for the total distance traveled by the object using the following:
Divide the first equation by the second equation
God bless....I hope the explanation is useful.
