A motorcyclist moves south through a small town at a velocity of 10.m⋅s−1. She then starts to accelerate at a constant 5.0m⋅s−2 for 5.0 seconds. a. Calculate the distance she has travelled during this 5.0 second time interval. (2)

b. Determine her velocity at the end of the 5.0 second time interval. (2)

c. The motorcyclist then starts to cruise at constant speed. If the dissipative forces acting against the motion of the motorcyclist and motorcycle total 12N, what is the power dissipated? (2)
