Can you help me solve this workshet

Problem 1: A block of mass m starts from rest and slides down a frictionless semi-circular track from a height h as shown below. When it reaches the lowest point of the track, it inelastically collides with a stationary piece of putty also having mass 2 m . The block and the putty stick together and continue to slide. What is the maximum height that the block-putty system could reach? Note: The diagram is NOT to scale, so do not use it to estimate your answer. Your answer should be in terms of the variables provided and g (acceleration due to gravity}. ' What is/are the key principle(s) will you need to help solve the problem? ' What assumption(sllapproximationls) do you need to help you solve the problem? ' Identify your system (object experiencing a change) and surroundings (i.e., objects causing the change). \" In words, describe the general strategy you will take to solve the problem. How will you apply the principles and assumptions/approximations you identified? ' Solve the problem. Clearly and neatly work out the solution. Problem 2 A block of mass m starts from rest and slides down a frictionless semi-circular track from a height h as shown below. When it reaches the lowest point of the track, it collides elastically with another block of mass 2 In . What are the heights that the each of the two blocks reach after the collision? Your answers should be in terms of m . h . and g .
