Question

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?

Answer 1

Step-by-step 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.

Answer 2

The answer is 38.33 kg

Step-by-step explanation:

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

`m = (p)/(v) \\`

where

p is the momentum

v is the velocity

So we have

`m= (345)/(9.0) \\ = 38.333333...`

We have the final answer as

38.33 kg
