A cyclist does work at the rate of 500 w while riding. how much force does her foot push with when she is traveling at 8.0 m/s?

Respuesta :

TammyP
P=F*V
F=P/V
F=500W/8=62.5N

Answer:

The foot push of the cyclist exerted a force of 63 Newton.

Explanation:

Given data

  • Power (P): 500 Watt
  • Velocity (v): 8.0 m/s
  • Force (F): ?

We can find the force exerted by the foot push of the cyclist using the following expression.

P = F × v

v = P/F = 500 W/ (8.0 m/s) = 63 N

The foot push of the cyclist exerted a force of 63 Newton.
