A 1 kg pendulum is held 2 meters above the ground and released. How fast is the pendulum traveling when it reaches it's lowest point? Assume the acceleration of gravity is 10 m/s^2.

A bowling ball is attached to a 3.87-meter long cable and hung from the ceiling. The cable is kept taut and the ball is raised to an initial height of 1.61 meters above the classroom floor. It is released from rest and allowed to swing as a pendulum. Determine its speed (in m/s) when it is at a height of 1.12 meters above the floor. (Use g=10 m/s/s) Answer: _________ m/s  (round to the nearest hundredth)

Fx (N) 3 2 1 x (m) 0 2 46 8 10 12 14 16 What is its speed at the following positions? (a) x = 5.00 m m/s (b) x 10.0 m m/s (c) x = 15.0 m m/s

A simple pendulum is suspended from the ceiling by means of a string and has a length of 1.56 m long. Suppose you start with the pendulum hanging vertically, at rest. You then give it a push so that it starts swinging with a speed of 1.73 m/s. What maximum angle (in degrees) will it reach, with respect to the vertical, before falling back down?     38.3 degrees     31.9 degrees     25.5 degrees     20.4 degrees
