Question

A 5 kg ball is moving at a velocity of +2 m/s when it

Answer 1

Heya!!

For calculate aceleration, lets applicate formula:

                                                   $\boxed{a=\frac{V-V_o}{t} }$

                                                   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:

$\boxed{a=\frac{5\ m/s - 2 \ m/s}{7\ s} }$

⇒ Resolving

$\boxed{ a=0,428\ m/s^{2}}$

Result:

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

Good Luck!!
