The accompanying figure shows the velocity y = ds/dt = ƒ(t) (m/ sec) of a body moving along a coordinate line.

a. When does the body reverse direction?

b. When (approximately) is the body moving at a constant speed?

c. Graph the body’s speed for 0 ≤ t ≤ 10.

d. Graph the acceleration, where defined.
