Question

a motorcyclist starts from rest and accelerates at rate of 4 meters per second squared north. what is the final velocity of the motorcycle if travels for 20 seconds.

Answer 1

80m/s

Step-by-step explanation:

Final velocity is given by

v=u+at

when a motorcyclist starts from rest, initial velocity (u) =0

therefore

v=0+4*20

v=80m/s

that's the answer
