Compute all parts of following problem:
Problem: At t=1.0s, a 0.70kg object is falling with a speed of 6.0 m/s. At t=2.0s, it has a kinetic energy of 25 J.
Part I: What is the kinetic energy of the object at t=1.0s?
Part II: What is the speed of the object at t=2.0s?
Part III: How much work was done on the object between t=1.0sand t=2.0s?
I want help to find how much work was done on the object between t=1.0sand t=2.0s.
