A motorbike accelerates from rest to 12 m/s in 3 s on a level road. If the force is 3000 N, what is the total mass of the cyclist and the motorbike?

Answer 1

To determine the acceleration we know the inital velocity (0), final velocity and time token

Thus v=v_o+at so 12=0+3a so a = 4m/s

Also force is given by F=ma

Thus m= F/a =3000/4 =750kg
