Question(I) A horizontal force of 310 N is exerted on a 2.0kg2.0-\mathrm{kg} ball as it rotates (at arm's length) uniformly in a horizontal circle of radius 0.90 m . Calculate the speed of the ball.

Studdy Solution
Take the square root of both sides to solve for v v :
v=139.5 v = \sqrt{139.5}
v11.81m/s v \approx 11.81 \, \text{m/s}
The speed of the ball is approximately:
11.81m/s \boxed{11.81 \, \text{m/s}}
