AP Physics C: Mechanics Question of the Day

Test your knowledge with a hand-picked multiple-choice question.

Object A has mass $\small 1.0kg$ and initially moves to the right at $\small 6.0$\frac{m}{s}$$ . It then collides with object B, which has mass $\small 5.0kg$ and was initially moving to the right at $\small 4.0$\frac{m}{s}$$ . If the two objects stick together after the collision, what percentage of the initial kinetic energy has been dissipated?
