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 :
[tex]p=mv[/tex]
where,
p = momentum
m = mass
v = velocity
Now put all the given values in the above formula, we get the velocity of a skateboarder.
[tex]100\text{Kg m/s}=15Kg\times v[/tex]
[tex]v=6.67m/s[/tex]
Therefore, the velocity of a skateboarder is, 6.67 m/s
