A wooden sphere of mass 420 g (0.420 kg) hangs motionless from a pendulum arm. A projectile of mass 26 g (0.026 kg) travels a straight line path with a velocity of 350 m/s. The projectile hits and passes through the center of the wooden sphere which leaves a hole through the sphere and causes the sphere to start a pendulum swing. The projectile exits the sphere with a new velocity of 170 m/s. The wooden sphere has a new mass of 310 g (0.310 kg) as a result of the hole in it. The pendulum arm has a length, L, of 26 m. a) What is the velocity of the wooden sphere after the projectile has passed through it? b) How much work was done to make the hole in the wooden sphere? c) What was the maximum vertical deflection, Ah, achieved by the wooden sphere? d) What was the maximum angle of deflection, 0, achieved by the wooden sphere?
