Question

a bodytravelling with a velocity of 100ms-¹accelerates uniform 10ms-² a period of 20 second calculate the velocity and the distance travelled in 30 second​

Answer 1

Given,

u= 100 m/s

a= 10 m/s^2

t = 20 s

So,

We know,

v = u + at

v = 100 + 10 x 20

v = 300 m/s

Distance travelled,

s = {(v + u) / 2} x t

= {(300 + 100) / 2 } x 20

= (400 / 2 ) x 20

= 200 x 20

= 4000 m
