accelerate a trolley of mass 20g Through 1m/s2.​

Answer 1

Explanation:

When a bus travels, its motion cannot be uniform in practice. ... If any luggage kept on the roof of the bus is not tied with a rope, then it tends to move forward due to its inertia. In this process, it could fall off the bus. Therfore, it is advised to tie any luggage kept on the roof of a bus with a rope.
