Consider a conical pendulum with a bob of mass m=82.0 kg on a string of length L=10.0 m that makes an angle of theta=8.00 degrees with the vertical. (Consider +i to be towards the center of the circular path and +j to be upward).
(a) Determine the horizontal and vertical components of the force exerted by the string on the pendulum.
(b) Determine the radical acceleration of the bob.
After impact, the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.650, illustrate what was the speed of the bullet immediately before impact?
