Answer 1

Answer: - 1000 Newton

Explanation:

Initial velocity, u = 90 km/h or 25 m/s.

Final velocity, v = 0 as coz it stops

Mass = 200 kg

Now, force exerted by the brakes will be the acceleration they produce to stop the motorcycle.

Therefore we will use the formula, v = u +a t

v= u+ at

0= 25 + a * 5

-25= a* 5

Therefore, force exerted by the brakes is -1000 N to stop the motorcycle.

-5= a

Now, force exerted = product of mass and acceleration

= 200* -5

= -1000 N
