A 0.330-kg volleyball is thrown vertically downward with a speed of 0.150 m/s. It takes it 0.0655 s to reach the ground. What is the magnitude of its momentum just before it hits the ground?
A) 0.212 kg∙m/s
B) 0.262 kg∙m/s
C) 0.163 kg∙m/s
D) 0.0216 kg∙m/s
E) 0.0418 kg∙m/s

Quizplus · Accepted Answer

The momentum of an object is given by the product of its mass and velocity. The final velocity can be calculated using the initial velocity, acceleration due to gravity, and time. The final velocity is approximately 0.794 m/s, and the momentum is 0.330 kg * 0.794 m/s = 0.262 kg∙m/s.
