Explanation:
A 500 g ball swings in a vertical circle at the end of a 1.4-m-long string. when the ball is at the bottom of the circle, the tension in the string is 18 n.
We know that the formula for the centripetal force is:
F = m·v² / r
Solving for v we get:
v = √(F · r / m)
= √(36 N · 5.0 m / 20 kg)
= 3.0 m/s
The stroller moves at a speed of <span>3.0 m/s.</span>
