A wagon is moving with a velocity of -2.0 m/s while having a 20 kg mass on top of it. There is a force applied to the wagon over a distance of 3 m. It then comes to a stop with a velocity of 0m/s. Please answer the questions. Show all work.
1. What is the total work done on the wagon?
2. What was the average force applied to the box to bring it to a halt?

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...

A hammer of mass m = 0.45 kg is moving horizontally at a velocity of v = 6.5 m/s when it strikes a nail and comes to rest after driving the nail a distance Δx = 0.95 cm into a board. What is the duration of the impact, in seconds, assuming the acceleration of the hammer was constant? What was the average force, in newtons, exerted on the nail?
