A3,568 kg elephant is riding a bicycle at a speed of 43 m/s. out of nowhere, a zebra runs out in the elephant's path and he must slam on his brakes. if the bicycle's brakes exert a stopping force of -1 kn, how far will it take to stop the bicycle?

3302 meters!

Explanation:

Wow!

The acceleration due to the stopping force of the brakes is given by Force/mass = 1000/3568 =.28m/s^-2

We will apply the equations of motion to calculate the braking distance.

; where V is the final velocity, U is the initial velocity, a is the acceleration and s is the displacement.

0=43^2-2(0.28)*s

Solve for s.

answer is c
