You find an abandoned car in a Walmart parking lot. The car is locked. You look up the car on Kelly’s Blue Book and find the mass to be 1200 kg. You go and push the car. How much force would you have to apply to get the car to start sliding? If you continued to apply this same force, determine the acceleration of the car. If you pushed for 20 s, how far would the car travel?

A crate of mass m = 24 kg rides on the bed of a truck attached by a cord to the back of the cab as in the figure below. The cord can withstand a maximum tension of 64 N before breaking. Neglecting friction between the crate and truck bed, find the maximum acceleration the truck can have before the cord breaks. (Enter the magnitude of the maximum acceleration in the forward direction.) m/s?
A 2100 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 N. What is the maximum possible acceleration the truck can give the SUV? At this acceleration, what is the force of the SUV's bumper on the truck's bumper?

A man stands on a scale in an elevator that is accelerating upward. The scale reads 973.8 N. When he holds a 44.0 kg box, the scale reads 1449.8 N. What is the man's mass? and What is the magnitude of the acceleration of the elevator?
A 1,200-kg car is pulling a 315-kg trailer. Together, the car and trailer have an acceleration of 2.10 m/s? in the positive x-direction. Neglecting frictional forces on the trailer, determine the following. (Indicate the direction with the sign of your answer. Assume forward motion is along the positive x-axis and upwards is along the positive y-axis. Assume the trailer's weight is entirely supported by it's own tires.)

A person pushes a 0.20 kg lunch tray across a table, and it slows down as it slides because of friction. The coefficients of friction between the tray and the table are µs = 0.15 and µk = 0.11. What would the acceleration of the tray be?
You have gone skiing at the Poconos. You (mass 45 Kg) are being pulled up a 300 snow-covered slope by a tow rope at constant speed 0.5 m/s. Ignore friction. Calculate the normal force on you and the tension in the rope. (Hint: Draw a force diagram, i.e., all the forces acting on you.) a) Normal force = 382 N, Tension = 220.5 N b) Normal force = 220.5 N, Tension = 382 N
Alice and Bob had car trouble. Their car broke down and Bob could not restart it. Alice got out to push the car and after some time she asked Bob if he would trade jobs with her for a while. Bob answered, "It won't matter if I do. I took physics, and I know that no matter how hard I push on the car, it will push back on me just as hard so I won't accomplish anything. That's Newton's Third Law and it is always true. It has been tested millions of times. It wouldn't matter if I pushed the car. I wouldn't be able to push it anywhere." Aside from the fact that his relationship with Alice is probably fınished, which of the following correctly explains a flaw in Bob's logic? The third law says that the two forces he is talking about are only approximately equal. The third law does not apply in this case because the car is on wheels. O The two forces he is talking about are on two different objects. Thw two forces will not be the same because the two masses are different. The third law only…
