Question

What force will change the velocityOf an objectof mass2.5kgfrom 5m/sTo 10m/sin 5 sec

Answer 1

Answer:

Force required is 2.5 N

Explanation:

we know that force = mass X acceleration

acceleration = final velocity - initial velocity/ time

                     = 10 m/s - 5 m/s

                              5 sec

                     = 5 m/s

                        5 sec

                     = 1 m/s²

Force = mass X acceleration

          = 2.5 kg X 1 m/s²

          = 2.5 N
