Answer:

The answer is 38.33 kg

Explanation:

The mass of the teenager and his RipStick can be found by using the formula

[tex]m = \frac{p}{v} \\ [/tex]

where

p is the momentum

v is the velocity

So we have

[tex]m= \frac{345}{9.0} \\ = 38.333333...[/tex]

We have the final answer as

38.33 kg

Hope this helps you

Answer:

Explanation:

The momentum = 345 kg m/s

The velocity = 9.0 m/s

The mass = ?

345 kg m/s = 9.0 m/s * m      divide by 9

345 kg m/s / 9 = 9 /9 * m

38.3 kg            = m

There are 2 sig digs. so the answer should be 38 kg.
