# Question

A simple pendulum of length 2.00 m is released from a horizontal position. When it makes an angle of from the vertical, determine

(a) Its angular acceleration,

(b) Its centripetal acceleration, and

(c) The tension in the string. Assume the bob’s mass is 1.50 kg.

## Answer to relevant Questions

From the known mass and radius of the Moon (see the tables inside the back cover of the book), compute the value of the acceleration due to gravity, gM, at the surface of the Moon. A man has a mass of 75 kg on the Earth’s surface. How far above the surface of the Earth would he have to go to “lose” of his body weight? (a) What is the mutual gravitational potential energy of the configuration shown in Fig. 7.36 if all the masses are 1.0 kg? (b) What is the gravitational force per unit mass at the center of the configuration? Venus has a rotational period of 243 days. What would be the altitude of a synchronous satellite for this planet (similar to geosynchronous satellite on the Earth)? The hour, minute, and second hands on a clock are 0.25 m, 0.30 m, and 0.35 m long, respectively. What are the distances traveled by the tips of the hands in a 30min interval?Post your question
