This question is about force, mass and acceleration.
A motorcycle starts from rest and accelerates at 4.5 m/s24.5\text{ m/s}^24.5 m/s2.
Use the equation: Acceleration=Change in velocityTime taken\text{Acceleration} = \frac{\text{Change in velocity}}{\text{Time taken}}Acceleration=Time takenChange in velocity
Calculate the velocity of the motorcycle after 6 s6\text{ s}6 s.
A motorized skateboard moves along a track with an acceleration of 3 m/s23\text{ m/s}^23 m/s2.
The force on the skateboard and its rider is 270 N270\text{ N}270 N.
Harnessing Newton's second law, calculate the mass of the skateboard and its rider.
