# A 2.0-kg ball is moving with a constant speed of 5.0m/s in a horizontal circle whose diameter is 1.0 m. What is the magnitude of the net force on the ball?

Dec 8, 2015

$100 \text{N}$

#### Explanation:

The centripetal force on the ball is given by:

$F = \frac{m {v}^{2}}{r}$

$\therefore F = \frac{2 \times {5}^{2}}{0.5}$

$F = 100 \text{N}$
