Q1. A parachutist descending at a speed of -13.0 m/s loses a shoe at the altitude of 54.0 m.

(a) when does the shoe reach ground?

(b) What is the velocity of the shoe just before it hits the ground?

Q2. An object whose weight is 100 Ibf experiences a decrease in kinetic energy of 500 ft. Ibf and an increase in potential energy of 1600 ft. Ibf. The initial velocity and elevation of the object, each relative to surface of the earth, are 50 ft/s and 40 ft, respectively. If g= 36.2 ft/s^2, conclude

(a) final velocity, in ft/s

(b) final elevation, in ft.
