Question

a body accelerates uniformly from 10m/s to 15m/s in 5s. Find
1 - The velocity of the body after next 5 seconds.
2 - The distance covered by the body in that time​

Answer 1

First

Initial velocity of the body = 10m/s

final velocity of the body = 15m/

Time taken = 5s

uniform accelaration = (15-10)/5 = 1m/s²

velocity after next 5s = 20m/s

Because the body is in uniform motion

Distance travelled = (v+u)/2×t

v = 20m/s

u = 15m/s

time = 5s

distance = s = (20+15)/2×5 = 175/2 = 87.5m ans
