ANSWER:
Solution 48P
Problem (a)
Step 1:
Length of the wheelbase of the pickup truck L = 3.00 m
Force exerted by the ground on the front wheels W1 = 10,780 N
Force exerted by the ground on the rear wheels W2 = 8820 N
Weight of the box W3 = 3360 N
Position of the box behind the rear wheels x = 1.00 m
Total weight of the truck W = W1 + W2 = 19,600 N
