Question

a bus of mass 4000 kg starts from rest and rolls down hill with constant acceleration. if it travels a distance of 800 m in 10 s . find its acceleration

Answer 1

Dear student

$$\begin{gathered} U\sin gtheformula \\ s=ut+\frac{1}{2}a{t}^2 \\ 800=0\times t+\frac{1}{2}a\times {10}^2 \\ 800=\frac{100}{2}\times a \\ 800=50\times a \\ a=\frac{800}{50}=16m/s^2 \\ Regards \end{gathered}$$
