Question
The speed of a 4-kg ball with a momentum of 12 kg m/s is Group of answer choices3 m/s.3 m/s2.12 m/s.12 m/s2.
Solution
The momentum (p) of an object is given by the product of its mass (m) and velocity (v). This relationship is expressed in the formula:
p = m * v
We can rearrange this formula to solve for velocity:
v = p / m
Given that the mass of the ball is 4 kg and its momentum is 12 kg m/s, we can substitute these values into the formula:
v = 12 kg m/s / 4 kg = 3 m/s
So, the speed of the 4-kg ball with a momentum of 12 kg m/s is 3 m/s.
