Textbook Question

Chapter 8, Problem 35P

A block of ice with a mass of 2.50 kg is moving on a frictionless, horizontal surface. At t = 0, the block is moving to the right with a velocity of magnitude 8.00 m/s. Calculate the magnitude and direction of the velocity of the block after each of the following forces has been applied for 5.00 s: (a) a force of 5.00 N directed to the right; (b) a force of 7.00 N directed to the left.
