A ballistic pendulum of length L= 0.24 meters is essentially massless except for a weight of mass mw = 0.24 at the end. A projectile of mass mp = 0.17 kilograms was fired at the pendulum from left to right. The projectile had an initial speed vi before it collided with the pendulum a distance d = 0.08 meters above the weight at the end. The projectile became lodged in the pendulum which swung to the right to a maximum angle of θ m a x= 45 degrees from vertical, as shown in the diagram above. Aside from what happened when the projectile became lodged in the pendulum, ignore all sources of friction and let g = 9.8 meters per second squared. What was the initial speed vi (in units of meters per second) of the projectile

An asteroid has a mass of m = 2.6 x 106 kg and is approaching Earth. When the asteroid is exactly 3 radii away from the Earth's centre, it's speed relative to the Earth's centre is u = 8.7 x 103 ms-1. The asteroid then falls to the Earth's surface, but remains intact without dissipating any energy as it passes through the Earth's atmosphere. If the rotation of the asteroid and the Earth is ignored, what is the kinetic energy of the asteroid just before it hits the ground?
