With an average acceleration of −1.6 m/s^2,
how long will it take a cyclist to bring a bicycle
with an initial speed of 13.3 m/s to a complete
stop?
Answer in units of s
Answered by Bri
(A)Acceleration = -1.6 m/s
Vi = 13.3 m/s
Vf = 0
T(time) = ?

T = Vf-Vi/A
T = 0-13.3/-1.6
T = 8.3125 s

A robot drops a camera off the rim of a 239 m height cliff on Mars, where the free- fall acceleration is -3.7 m/s2 .

Find the velocity with which the camera hits the ground.

Find the time required for it to hit the ground.
