I NEED SOLUTION TO PART#8

The two objects as pictured make a completely elastic collision. (Problems 1,2) 1. What is the change in energy for the object that was initially at rest (in terms of vo, m, theta)? 2. What is the angle theta (in terms of m and vo)? The object as shown slides up the ramp, which is free to roll on á frictionless surface. (Problems 3-5) 3. What is vf for the two objects (in terms of m, theta, g, vo, H)? 4. What is the total change in energy of the small mass? 5. What is the change in the internal energy of the two object system? A thread is drawn from the inside of a box of mass M initially at test on a frictionless surface. You pull thread by applying a force F to the thread, and when the box has moved a distance L and a length d has been removed from the box: (Problem 6-8) 6. How fast is the box moving (in terms of L, d, m, F)? 7. What is the change in the internal energy of the box (in terms of L, d, m, F)? 8. How much time does this process take (in terms of L, d, m, F)?

Answers

m a = To acceslation rope tension as at rope is mass less Point B T-F=0 2) T=F . Now; a FB2. 17o. - EF=ma T= ma - T= F ... EHere box will not move until thread become tight it will take no time .

And after that the force from rope tension which is equal to the applied force start acting on the block. And aftef that the block will take certain time t to move distance L.

Ask if doubt
