An Olympic long jumper is capable of jumping 7.6 meters. Suppose that his horizontal speed is 8.5 m/s as he leaves the ground. Evaluate how high does he go? Suppose that he lands standing upright, that is, the same way he left the ground.
A projectile of mass 2.0 kg approaches a stationary target body at 5.0 m/s. The projectile is deflected through an angle of 59.5° and its speed after the collision is 2.8 m/s. What is the magnitude of the momentum of the target body after the collisi..
