What is the potential energy of a 12 kg box on a 5 m high shelf?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
