Chapter 1, Problem 7P

The velocity v (r ) of a ball thrown upward satisfies the equation $v\left(t\right)=v_o+at$, where v₀ is the initial velocity of the hail in m/s and a is the acceleration in m/s².

(a) Given the data in Fig. P1.7. find the equation of the line representing the velocity v (r ) of the ball, and determine both the initial velocity v0 and the acceleration a.

(b) Sketch the graph of the line v (t ), and clearly indicate both the initial velocity and the acceleration on your graph. Also determine the time at which the velocity is zero.
