A projectile with a mass of 2.4 kg is fired from a cliff 125 m high with an initial velocity of 150 m/s, directed 41.0º above the horizontal. What are (a) the kinetic energy of the projectile just after firing and (b) its potential energy? (c) Use conservation of energy to find the speed of the projectile just before it strikes the ground.
