The body, starting off and moving uniformly accelerated, at the end of the 5th second had a speed of 10 m / s.

The body, starting off and moving uniformly accelerated, at the end of the 5th second had a speed of 10 m / s. What path has it traveled during this time and what is its average speed along this path?

Since the motion is uniformly accelerated, the following equation for the speed is valid:
V = a * t
Let’s substitute:
a = 10/5 = 2m / s ^ 2
S = 2 * 25/2 = 25m
Vav = S / t = 25/5 = 5m / s
