a. a = (V-Vo)/t.
V = 510 m/s
Vo = 0
t = 2.37 s.
b. a = (V-Vo)/t
V = 0
Vo = 510 m/s.
t = 3.15 s.
Note: Acceleration when braking will be
negative.
Rocket-powered sleds are been used to test the responses of humans to acceleration. Start- ing from rest, one sled can reach a speed of 510 m/s in 2.37 s and can be brought to a stop again in 3.15 s.
Find the acceleration of the sled while ac- celerating.
Answer in units of m/s2
