A 5.0 kg bike moving 10 m/s comes to a complete stop in 2 seconds. What is the average force of the brakes on the bike?

25 N

Explanation:

Force : This is defined as the product of mass and acceleration. The unit of force is Newton or kgm/s².

From the question,

F = ma Equation 1

Where F = Force of the brake, m = mass of the break, a = acceleration.

But,

a = v/t Equation 2

where v = velocity, t = time.

Substitute equation 2 into equation equation 1

F = m(v/t) Equation 3

Given: m = 5.0 kg, v = 10 m/s, t = 2 seconds

F = 5(10/2)

F = 25 N.

Hence the average force of the brakes on the bike is 25 N

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
