SP2. As described in example box 6.2, a 120-kg crate is acceler- ated by a net force of 96 N applied for 4 s. a. What is the acceleration of the crate from Newton's sec- ond law? b. If it starts from rest, how far does it travel in the time of 4 s? (See section 2.5 in chapter 2.) c. How much work is done by the 96-N net force? d. What is the velocity of the crate at the end of 4 s? e. What is the kinetic energy of the crate at this time? How does this value compare to the work computed in part c?
