Disk A (ma=8kg) which is initially moving with vAI= 20m/s towards right undertakes a central impact with disk B (mg=12kg) which moves with VBI=4m/s also towards right. After the impact, both disks move towards right. Determine the velocities of the disks after the impact, knowing that the coefficient of restitution is e30.87 and the disks move on a frictionless surface.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

Disk A (ma=8kg) which is initially moving with vAI= 20m/s towards right
undertakes a central impact with disk B (mg=12kg) which moves with VBI=4m/s
also towards right. After the impact, both disks move towards right. Determine
the velocities of the disks after the impact, knowing that the coefficient of
restitution is e=0.87 and the disks move on a frictionless surface.
