Question

Doug used a magnet to move a .025kg ball. The magnet exerts a force of 5N, which causes the ball to begin moving. What is the acceleration of the ball when it begins to move?

Answer 1

`a=200\ m/s^2`

Step-by-step explanation:

Given that,

The mass of a ball, m = 0.025kg

The force exerted by the magnet, F = 5 N

We need to find the acceleration of the ball when it begins to move. Let a be the acceleration. The net force of the ball is given by :

F = ma

Where

a is acceleration of the ball

`a=(F)/(m)\\\\a=(5)/(0.025)\\\\a=200\ m/s^2`

so, the required acceleration of the ball is
`200\ m/s^2`.
