Question

A cart rolling down an incline for 5.0 seconds has an acceleration of 4.0 m/s2. If the cart has a beginning speed of 2.0 m/s, what is its final speed?

Answer 1

`22 ms^-1`

Explanation:

Applying `v=u+at` (all the symbols are bearing their conventional meaning)

Here,`u=2ms^-1,t=5,a=4ms^-2`

So,`v=2+4*5=22ms^-1`
