Question

What is the velocity of a skateboarder whose momentum is 100 kg-m/s and mass is 15 kg? Round to the nearest hundredth. A. 3.33 m/s B. 13.25 m/s C. 6.67 kg D. 6.67 m/s

Answer 1

Answer: D

Explanation: 100/15 =6.67 I hope this is right.

Answer 2

Answer : The correct option is, (D) 6.67 m/s

Explanation : Given,

Momentum = 100 Kg m/s

Mass = 15 Kg

Momentum : It is defined a the product of mass and the velocity of an object.

Formula used :

`p=mv`

where,

p = momentum

m = mass

v = velocity

Now put all the given values in the above formula, we get the velocity of a skateboarder.

`100\text{Kg m/s}=15Kg* v`

`v=6.67m/s`

Therefore, the velocity of a skateboarder is, 6.67 m/s
