Question

A particle starts from rest moving with constant acceleration 1m/s². Then velocity of particle when it covers a distance of 50m is
1. 100m/s
2. 50m/s
3. 5m/s
4. 10m/s
​

Answer 1

$v {}^{2} = u {}^{2} + 2as$

v:,?

u:0

a:1m/s²

s:50m

v²:u²+2as

v²: 0 +2*50

v²:100

v:√100

v:10m/s

hence the answer is 4.)10m/s
