Rocket-powered sleds are been used to test the responses of humans to acceleration. Starting from rest, one sled can reach a speed of 533 m/s in 2.45 s and can be brought to a stop again in 2.37 s. Find the acceleration of the sled when braking. Answer in units of m/s^2

(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
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
A 0.05 kg arrow with the velocity of 180 m/s is used to shoot a 5 kg block of wood off the top of a log. What will be the velocity of the arrow and wood after contact?
A 1 kg poodle running right at 3 m/s has an elastic head on collision with a 9 kg basset hound walking left with a velocity of 1 m/s. After the collision the poodle bounces off to the left at 3 m/s. Whats the basset hounds velocity after the colllision?
