Question

A cyclist riding in a straight line has an initial velocity of 3.5 m>s, and accelerates at -1.0 m>s2 for 2.0 s. The cyclist then
coasts with zero acceleration for 3.0 s, and finally accelerates at 1.5 m>s2 for an additional 2.0 s. (a) What is the final
velocity of the cyclist? (b) What is the average acceleration of the cyclist for these seven seconds?
