Answer:
6.67 m/s
Step-by-step explanation:
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 :
where,
p = momentum
m = mass
v = velocity
Now put all the given values in the above formula, we get the velocity of a skateboarder.
Therefore, the velocity of a skateboarder is, 6.67 m/s

ABC and CBH are right angles
DBC = 90 - 37 = 53
CBJ = 90 - 31 = 59
HBD = 180 - 37 = 143
or
HBD = 31 + 53 + 59 = 143 :)
