A trolley, while going doen an inclined plance, has an acceleration of 2 `cm s ^(-2).` What will be its velocity 3 s after the start ?

Text Solution

Verified by Experts

Here, `u = 0,a =2 cm s ^(-2) ,t =3 s `
`v=u +at`
`= 0 + 2 xx 3 = 6 cm s ^(-1)`
The velocity of the trolley will be `6 cm s ^(-1).`
