Problem 15.79 2 of 3 I Review The two disks A and B have a mass of 4 kg and 5 kg , respectively. They collide with the initial velocities shown. The coefficient of restitution is e = 0.7. Suppose that (vA)1 = 6 m/s, (vB)1 = 8 m/s. (Figure 1) Part A Determine the magnitude of the velocity of A just after impact. Express your answer to three significant figures and include the appropriate units. ? Figure 1 of 1 > m (va)2 = |4.899| S (VB)1 Submit Previous Answers Request Answer B A (Vah 60 Line of impact X Incorrect; Try Again; 3 attempts remaining Part B Determine the angle between the x axis and the velocity of A just after impact, measured clockwise from the negative x axis. Express your answer using three significant figures.

Forms of Energy

Energy is described as the capability to accomplish a task, like the ability to push a block by applying force on it. It is a quantitative property that is used to accomplish work on an object.
