Question

A trolley going down an inclined plane has an acceleration of 2cm/s^2 What will be its velocity

3s after the start.​

Answer 1

`V_(f)` = 6 cm/s

Step-by-step explanation:

Given:

Acceleration = a = 2 cm/s²

Time = t = 3s

Initial Velocity =
`V_(i)` = 0 cm/s

Required:

Velocity =
`V_(f)` = ?

Formula:

a =
`(V_(f)-V_(i))/(t)`

Solution:

2 =
`(V_(f)-0)/(3)`

=>
`V_(f)` = 2*3

=>
`V_(f)` = 6 cm/s
