The momentum of a teenager and his is 345 kg m/s, . Their velocity of is 9.0 m/s. What is the combined mass of the teenager and his RipStick?

Explanation:

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

where

p is the momentum

v is the velocity

So we have

We have the final answer as

Hope this helps you

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.
