The mass of the ball is 6.67 kg
Explanation:
The momentum of an object is given by:
where
p is the momentum
m is the mass of the object
v is its velocity
It must be noted that momentum is a vector quantity, so it has both magnitude and direction (but here only the magnitude is given).
For the ball in this problem, we have:
v = 1.5 m/s is its velocity
p = 10.0 kg m/s is its momentum
Solving the formula for m, we find the mass of the ball:
