Question

A bowling ball weighing 71.2 NN is attached to the ceiling by a 3.50 mm rope. The ball is pulled to one side and released; it then swings back and forth like a pendulum. As the rope swings through its lowest point, the speed of the bowling ball is measured at 4.40 m/s.

Part A

At that instant, find the magnitude of the acceleration of the bowling ball.

Part B At that instant, find the direction of the acceleration of the bowling ball.

At that instant, find the direction of the acceleration of the bowling ball.

Upward

Downward

In the direction of motion

Part C: At that instant, find the tension in the rope.

Answer 1

Part A At the better point, the aceleration will be centripetal anduction, 4.40² 2 5.53 m/s 3.50 Part B The direction anduction will be of upwards Parte At the bottoms point, mut = To my Te muh ting > Te mua Tz (71.2/2.8 9.8) x 4.4 + 71.2 3.5 Tz 111.3875 N
