2. Suppose Andrea and Beatrice push horizontally, but in exactly opposite directions, on a wagon carrying food to a tailgate party. Andrea exerts a force of 85.0 N and Beatrice exerts a force of 100.0 N, friction is 12.0 N and the mass of the food and drink is 27.0 kg. (a) Define the system of interest and draw a free body diagram for it. (b) Calculate the acceleration of that system. (c) Find the acceleration for slightly larger friction of 15.0 N.

. Under certain conditions, the human body can safely withstand an acceleration of 10 g. (a) What net force would have to act on someone with mass of 50 kg to cause this acceleration? (b) Find the weight of such a person in pounds then convert the answer to (a) to pounds.
The wheels of a midsize car exert a force of 2100 N backward on the road to accelerate the car in the forward direction. If the force of friction including air resistance is 250 N and the acceleration of the car is 1.80 m/s2, what is the mass of the car plus its occupants? Explicitly show how you follow the steps in the Problem-Solving Strategy for Newton's laws of motion. For this situation, draw a free-body diagram and write the net force equation.
A block of mass m1= 10 kg is on a frictionless table to the left of a second block of mass m2 = 24 kg, attached by a horizontal string (Figure WU4.13). If a horizontal force of 120 N is exerted on the block m2in the positive x-direction, (a) use the system approach to find the acceleration of the two blocks. (b) What is the tension in the string connecting the blocks? (See Section 4.6.) Figure WU4.13
