012 (part 1 of 2) 1.0 points A particle of mass m = 8 kg is released from point A on a frictionless track at height ha 4.93 m. The acceleration of gravity is 9.8 m/s2 Determine the particle's speed at point B at height hb = 1.5 m. Answer in units of m/s. 013 (part 2 of 2) 1.0 points Determine the net work done by the force of gravity in moving the particle from A to B. Answer in units of J. 014 1.0 points A frictionless pendulum of length 3 m swings with an amplitude of 10°. At its maximum displacement, the potential energy of the pen- dulum is 10 J. What is the kinetic energy of the pendulum when its potential energy is 5 J? = 1. K = 15 J 2. K = 10 J 3. K = 5 J 4. K = 6.7 J 5. K = 3.3 J
