An object whose mass is 90 lb is projected straight upward from the surface of the earth and reaches a height of 900 ft when its velocity reaches zero. The only force acting on the object is the force of gravity. The acceleration of gravity is g = 32.2 ft/s². Determine the initial kinetic energy of the object, in ft·lbf, and the initial velocity of the object, in ft/s.

(a) During the packaging process, a can of soda of mass 0.4 kg moves down a surface inclined 20° relative to the horizontal, as shown in the figure below. The can is acted upon by a constant force R. parallel to the incline and by the force of gravity. The magnitude of the constant force R is 0.05 N. Ignoring friction between the can and the inclined surface, determine the can's change in kinetic energy, in J, and whether it is increasing or decreasing.
