A ball is attached to a horizontal cord of length L=1.01 m whose
other end is fixed, as shown.
If the ball is released, what will be its speed at the lowest point
of its path?
Correct, computer gets: 4.45 m/s

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.

A ball with mass m= 0.98 kg, is attached to a horizontal cord of length l = 59 cm whose other end is fixed. A peg is located a distance h = 12 cm directly below the point of attachment of the cord. After the ball is released, what will be the tension (in N) in the cord when it just starts its circular path about the peg?

20> A 5.15 kg ball is attached to the top of a vertical pole with a 2.29 m length of massless string. The ball is struck, causing it to revolve around the pole at a speed of 4.41 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g 9.81 m/s2. angle: What is the tension of the string? tension: N
