Explanation:

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+

Answer 2

Answer:

a) According To the Formula

Average Velocity Equal To Sum Of Initial Velocity and Acceleration Multiplied By Time

Average Velocity = Initial Velocity + Acceleration × Time

.

b)The Question is a bit improper
