1. A bicycle and rider with a combined mass of
115 kg are traveling at a speed of 8 m/s. What is the kinetic energy of the bicycle and rider?

Respuesta :

Answer:

3680 J

Explanation:

The kinetic energy of an object is given by:

[tex]K=\frac{1}{2}mv^2[/tex]

where

m is the mass of the object

v is the speed of the object

In this problem, we have

m = 115 kg is the combined mass of the bycicle and the rider

v = 8 m/s is the speed

Substituting numbers into the formula, we find

[tex]K=\frac{1}{2}(115 kg)(8 m/s)^2=3,680 J[/tex]

Answer:

3680 J
