Release Rope
A bowling ball weighs 71.2N is attached to the ceiling by a 3.80m rope.?
The ball is pulled to one side and released and swings back and forth. As the rope swings through its lowest point , the speed of the bowling ball is 4.20m/s. I need to find the magnitude and direction of acceleration at that instant. Also, the tension in the rope.
(4.2)^2/3.8 = 4.6m/s^2 The acceleration is directed upwards at this point.
Tension - weight = ma
Tension - 71.2 = (4.6)(7.3)
Tension = 104.6N
