10. A 3 kg ball on the end of a 2 meter string is released from rest from the horizontal position shown below. What is the te

Answer 1

Answer #1

V at lowest point = sqrt ( 2×9.8×2 ) = 6.261 m/s

T at lowest point = mg + mv²/r

T = 3×9.8 + 3×6.261²/2

T = 88.2 N -------------> Answer

A 1.9-kg ball is attached to the end of a 2.6-m string to form a pendulum. This pendulum is released from rest with a string horizontal. At the lowest point in its swing when it is moving horizontally, the ball collides elastically with a 2.5-kg block initially at rest on a horizontal frictionless surface. What is the speed of the block just after the collision? Show all the important physics steps.

1. (20 points) A pendulum consists of a small ball of mass m=2.00 kg that is suspended from a fixed point by a light string of length L=0.850 m (like the demonstration video.) The pendulum is released from rest when it is in its initial position with 0 =65.0°. Air resistance is negligible. a) Calculate the work done by gravity as the ball moves from the highest point of its semicircular path to the lowest point of its path. b)...
