Solution Summary: The author explains the velocity of the block of mass m and its momentum.
Two blocks of masses m and 3m are placed on a frictionless, horizontal surface.

2-3. Consider the situation of the reflection of a pulse at the interface of two string described in the previous problem. In addition to the net disturbances being equal at the junction, the slope of the net
disturbances must also be equal at the junction at all times. Given that p1 = 4.0 g/m, H2 = 9.0 g/m
and Aj = 0.50 cm find 2. A, (Answer: -0.10 cm) and 3. Ay. (Answer: 0.40 cm)please I need to show all work step by step problems 2 and 3
From number 2 and 3 I just want to show all problems step by step please do not short cut look for formula
Plz don't use chatgpt pls will upvote
