Question

A ball is being swung in a horizontal circle of radius .23 m at a rate of 7.8 m/s. If the ball has a mass of 0.63 kg, find the force of tension on the string.

Please show work

Answer 1

170 N

Step-by-step explanation:

Sum of the forces in the radial direction:

∑F = ma

T = m v² / r

T = (0.63 kg) (7.8 m/s)² / (0.23 m)

T = 170 N
