A 5 kg ball is moving at a velocity of +2 m/s when it speeds up to +5 m/s in 7 seconds.
Calculate the acceleration.

Heya!!

For calculate aceleration, lets applicate formula:

                                                   Δ   Being   Δ

                                          V = Final Velocity = 5 m/s

                                         Vo = Initial Velocity = 2 m/s

                                          a = Aceleration = ? m/s²

                                                   t = Time = 7 s

⇒ Let's replace according the formula:

⇒ Resolving

Result:

The aceleration of the object is 0,428 m/s²

Good Luck!!
