Question

A bus of mass 5000 kg starts from rest and rolls down a hill. If it travels a distance of 200 m in 10 s.Calculate acceleration of the bus and force.

Answer 1

Answer:

a=2m/s^2

F=10,000N

Explanation:

Acceleration a=v/t (1)

For v,

S=vt

v=S/t

v=20m/s put in (1)

a=20/10

a=2m/s^2

For F,

F=ma

F=5000kg×2m/s^2

F=10,000N
