Question

a body starts moving with an interval of 50 metre per second and acceleration 20 metre per second square who much distance it will covers in 4 seconds also calculate its average speed during this time interval​

Answer 1

Explanation:

Given -

u= 50m/s

a = 20m/s^2

t=4sec

s =?

s = ut + 1 / 2 at^2

s = 50×4+1/2×20×4×4

s = 200+160

s = 360m
