Question

. (a) Explain the meaning of the following equation of motion :
V=U + at
where symbols have their usual meanings.
(b) A body starting from rest travels with uniform acceleration. If it travels 100 m in 5 s, what is the value of
acceleration ?​

Answer 1

Answer:

(a) v=u+at is the first equation of motion. It gives the velocity acquired by a body in time t when the body has initial velocity u and uniform acceleration a.

(b) Initial velocity, u=0m/s

Time, t=5s

Distance, s=100m

Acceleration, a=?

s=ut+
