Question

Following are three equations of motion
`S(g)=ut+(1)/(2)at^(2) v(s)=sqrt(u^(2)+2as) v(t)=u+at`
Where `,S,u,t,a,v` are respectively the displacement `(` dependent variable `)`, initial `(` constant `)`, time taken `(` independent variable `)`, acceleration `(` constant `)` and final velocity `(` dependent variable `)` of the particel after time `t`.
Find the velocity of a particle after `100m-`
A. `10 m//s`
B. `20 m//s`
C. `30 m//s`
D. `0 m//s`

Answer 1

Correct Answer - B
`v=v+at`
`v=0+2xx10`
`=20m//s`.
