Homework Answers
for ball A , it is at rest so it will have only Potential energy = mgh
For ball B it will have Kinetic energy as well as Potential energy = mgh + 0.5mv^2
so it will be greater in case B
so the last option greater in case B is the correct answer

Two identical balls come into a collision with a coefficient of restitution e=0.8. Before the impact, VA = 7 m/s and V3 = 3 m/s. Their directions are as shown. Determine the magnitude of velocity of each ball after the impact. Include the following steps in your VB solution: a) Define a coordinate system appropriately. (3 pts) b) Calculate the two components of each velocity before the impact. (6 pts) c) Apply the right principle(s)/equation(s) to determine the component velocities...

HW 5.5. The drawing shows a top-view of a collision between two balls. Ball A has a mass of 0.03 kg and is moving along the positive c-axis at 5.5 m/s. It makes a collision with ball B, which has a mass of 0.05 kg and is initially at rest. The collision is not head-on. After the collision, the two balls fly apart with the angles shown in the drawing below. + 5.5 m/s At rest a) What are the...

The drawing shows four different situations in which a light ray is traveling from one medium into another. In some of the cases, the refraction is not shown correctly. For cases (a), (b), and (c), the angle of incidence is 42°; for case (d), the angle of incidence is 0°. Determine the angle of refraction in each case.
