Problem
A skateboarder starts from rest at the top of a straight, horizontal track. A small motor provides the board with a constant forward acceleration of magnitude 2.4m/s2 for the first 3.5s of motion. Neglect any frictional forces.
(a) Calculate the skateboarder’s speed at the end of the 3.5s interval. Show all work and include units with the final answer.
(b) Determine the skateboarder’s displacement from the starting point during the same time interval. Express your answer with appropriate units.
