# Kinematics Graph for Velocity

Please give step by step answers.

The four question that follow belong to the graph being described. The graph has velocit on the y axis in m/s and the x axis is time in seconds. The points given make the grph line. Points (0,20), (2,30), (4,40), (6,40), (8,0), and (10,-30).

1) What is the velocity of the object at t=2 seconds?

a) 30m/s

b) -30m/s

c) +5m/s

d) -5m/s

e) none of above

2) What is the acceleration of the object at t=2 seconds?

a) 30m/s

b) -30m/s

c) +5m/s

3) At what time is the magnitude of the velocity the greatest?

a) between 0 and 4 seconds

b) between 4 and 6 seconds

c) at 6 seconds

d) between 6 and 8 seconds

e) between 8 and 10 seconds

4) At what time is the magnitude of the acceleration the greatest?
