Calculate the maximum height that m1 and m2 rise after collision?

Click For Summary
SUMMARY

The problem involves calculating the maximum height that two blocks, m1 (2 kg) and m2 (10 kg), reach after an elastic collision on a frictionless track. Block m1 is released from a height at point A, which is part of a quarter-circle track with a radius of 4.9 m. The conservation of momentum and energy principles are applied to determine the velocity of m1 just before the collision at point B and subsequently the maximum heights reached by both blocks after the collision.

PREREQUISITES
  • Understanding of elastic collisions and conservation of momentum
  • Knowledge of gravitational potential energy and kinetic energy conversion
  • Familiarity with basic physics equations, including p=mv and y=1/2 at^2
  • Ability to analyze motion along a circular path
NEXT STEPS
  • Calculate the velocity of m1 at point B using energy conservation principles
  • Apply the conservation of momentum to find the final velocities of m1 and m2 after the collision
  • Determine the maximum height reached by both blocks using energy conservation post-collision
  • Explore the effects of different masses and heights on the outcome of elastic collisions
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and collision theory, as well as educators seeking to enhance their understanding of elastic collisions and energy conservation principles.

Homework Statement


Consider a frictionless track. Imagine point A to B is one quarter of a circle; point B to C is a horizontal flat plane; point C to D is also one quarter of a circle.

The block m1 is released from A. It makes a head-on elastic collision at B with m2 (that is initially at rest) Calculate the maximum height to which m1 and m2 rise after collision.

m1 = 2kg
m2 = 10 kg
radius of quarter circles = 4.9 m


Homework Equations


p=mv

m1vf + m2vi = (m1 + m2)v

y=1/2 at^2


The Attempt at a Solution


I am not quite sure how to attempt a solution.

Can you find out how fast m1 is going after it falls through the quarter of a circle A to B? Then you could do conservation of momentum on the collision at B.
 
I understand the equation for conservation of momentum, but how do I go about finding the velocity as you mentioned?
 
Draw the diagram. You should see how high above the BC horizontal section m1 is initially. From the initial height, you can calculate its speed after falling through the height either by using forces or energies.
