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?

The displacement of the elephant before it comes to a stop is 3301.8 m.

Explanation:

Given:

Mass of elephant is,

Initial velocity of elephant is,

Final velocity of elephant is,

Stopping force exerted by the brakes is,

As per Newton's second law, net force is equal to the product of mass and acceleration.

So, the stopping force is equal to the product of mass of elephant and stopping acceleration. Therefore,

Stopping force (f) = mass (m) × stopping acceleration

Now, using equation of motion, we find the total displacement of the elephant before it comes to a stop.

Let the total displacement be 'S'.

Using the equation of motion as below:

Therefore, the displacement of the elephant before it comes to a stop is 3301.8 m.

it has intertia. this is correct on edge nuity
