Answer» F =m ×am=1000kginitial VELOCITY = 36km/h36km \: PER \: hour = 36 \times \frac{5}{18} = 10 \: METR \: persecond36kmperhour=36× 185 =10metrpersecondfinal velocity = 0time = 5 secondsa = \frac{v - U}{t} = \frac{0 - 10}{5} = - 2a= tv−u = 50−10 =−2F = ma\begin{gathered} = 1000 \times ( - 2) = \\ = - 2000 \: newton\end{gathered} =1000×(−2)==−2000newton |
