Question

a body starts from rest it is uniformly accelerated for 20 seconds with accelerated 2ms -²
i-find velocity
and
ii-total distance Or
(ans i-40ms-¹ and ii- 400m)​

Answer 1

Answer:

1)Here,

u(initial velocity) =0

time(t)=20sec

acceleration(a) =2ms-²

v=u+at

v=0+2x20

v=40ms-¹

Velocity =40ms-¹

2)v²=u²+2as

(40)²=0²+2×2×s

1600=0+4s

4s=1600

s=1600/4

s=400m

Distance-400m
