A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?

A 128 lb person steps into an elevator at the ground floor. The elevator accelerates upward at 5.0 ft/s^2 until reaching a velocity of 24 ft/s. It then holds this velocity until decelerating (a=-5.0 ft/s^2) to a stop at the top floor. What is the normal force on the person in each of the three phases of this trip?

Superman is applying a 17,000 N horizontal force to try and stop a speeding locomotive. This train has a mass of {9004} kg, it is on level, horizontal track, and gravity in Metropolis is 10 N/kg. The train is originally travelling at 25 m/s, and the brakes have failed. (Friction force is zero). Draw a Force Body Diagram of the train, labelling and calculating all forces. What is the acceleration of the train? How many seconds does it take for Superman to stop the train? How far does the train travel in that time?

A 3 kg particle moves along an x axis, being propelled by a variable force directed along that axis. Its position is given by x = 2 m + (2 m/s)t + ct2 - (3 m/s³)t³ with x in meters and t in seconds.The factor c is a constant. At t = 4 s the force on the particle has a magnitude of 33N and is in the negative direction of the axis. What is c? Number Units
