A rock dropped on the moon will increase its speed from 0m/s to 8.15 m/s in 5 seconds what is the acceleration of the rock

Respuesta :

speed  Δv     =  v₂ =  8.15ms⁻¹

                     v₁ = 0ms⁻¹

time  =t = 5s

acceleration  =  a = speed / time taken

                          a =    Δv / Δt           ( as Δv = v₂ - v₁)

                          a  =   8.15ms⁻¹  /  5 s

                            a  = 1.6ms⁻²
