you can also calculate a ball’s speed with equipment you have at home. This procedure will measure the average speed of the pitch per second as it travels from the pitcher’s release point to home plate. You’ll typically convert this value to miles per...
A 0.020-kg ball tied to a string is placed on a flat table and the string is used to swing the ball around a horizontal circular path. If the string has a length of 0.58 meters and the ball moves with a speed of 1.1 m/s, what is the centripetal force acting on the...
Suppose that the pendulum is initially displaced by an angle of 60 degrees and then released from rest. Find the speed v Figure 4.2 shows two simple pendulums at the moment when they are released and allowed to swing freely. a. Which pendulum has the greater amplitude? b. Suggest why ...
