When a drag strip vehicle reaches a velocity of 60 m/s, it begins a negative acceleration by releasing a drag chute and applying its brakes. While reducing its velocity back to zero, its acceleration along a straight line path is a constant -6.0 m/s2 . What displacement does it undergo during this deceleration period?
a. 120 m
c. 320 m
b. 300 m
d. 240 m

Question 2

A vehicle designed to operate on a drag strip accelerates from zero to 30 m/s while undergoing a straight line path displacement of 60 m. What is the vehicle's acceleration if its value may be assumed to be constant?
a. 2.0 m/s2
c. 10 m/s2
b. 7.5 m/s2
d. 15 m/s2
