Please help me find a) and b):

A=3.33m/s

B=3.11m/s

Explanation:

Speed = total distance/time taken to cover distance

hence,

S=d/t

s=32.0/9.60

s=3.33m/s

acceleration due to gravity

v=u+at

that is (v=final velocity,u=initial velocity,a=acceleration and t= time)

from the formula

2.10=32.0+a*9.60

2.10=32.0+9.60a

CLT

9.60a=32.0-2.10

9.60a=29.9

a=29.9/9.60

a=3.11m/s

hope it correct!?

The velocity curve is such in which the x-axis is the velocity and the y is the time. The distance traveled by the object is calculated by multiplying velocity and time. Thus, in the velocity curve, the distance can be easily calculated if we know where to look.
