Hi, I need some assistance with the following questions:

Question: At the average rate of 15 m/s^2. How much time does it take for the complete increase in speed?
a. 0.25 s
b. 4.0 s
c. 0.0577 s
d. 17.3 s
e. 8.0 s

Question: A car traveling 20 m/s is able to stop in a distance d. Assuming the same braking force, what distance does this car require to stop when it is traveling twice as fast?
a. d
b. 2d
c. Squared 2d
d. 4d
e. Squared d
