Acart rolling down an incline for 5.0 seconds has an acceleration of 4.0 m/s .if the cart has an initial speed of of 2.0 m/s ,what's its final speed.

solve it with the following formula:

Vf = Vi + at

Final velocity = initial velocity + ( acceleration × time)

Explanation:

Putting the values

Vf = 2.0m/s+ 4.0m/s²× 5.0s

Vf = 2.0m/s +20.0 m/s (m/s² × s = m/s)

Vf = 22.0 m/s

attach the statements so i can answer : )
