A 10 kilogram block initially hangs at rest at the end of two 10 meter strings of negligible mass as shown on the left diagram above. A 0.009 kilogram bullet, moving horizontally with a speed of 1600 meters per second, strikes the block and becomes embedded in it. After the collision, the bullet/ block combination swings upward, but does not rotate. Use g=10 m/s 2
a)Calculate the speed v of the bullet/ block combination just after the collision. (m/s)
b)Calculate the ratio of the initial kinetic energy of the bullet to the kinetic energy of the bullet/ block combination immediately after the collision.
c)Calculate the maximum vertical height above the initial rest position reached by the bullet/block combination. (m)
