For this you would use the equation P = M x V
P ( momentum )
M ( mass - kg)
V ( velocity -m/s )
____________
Sams mass is 75 kg so you would fill in the "m" spot with 75
Sams velocity is 18 so you'd fill in the "v" spot with 18
_____
Your equation should look like this:
P = 75 x 18
From here is simple multiplication
75 x 18 = 675
Therefore your answer is p = 675
