Two metal spheres are suspended from the ceiling using massless non-bending rods as shown in the figure. Sphere 1 has mass m1 = 30.0 grams and is pulled to a height and released. After swinging down, mass 1 has an elastic collision with sphere 2 whose mass is m2 = 75.0 grams. (Use the center of each sphere as shown in the figure for distance purposes) 1.) Write the conservation of momentum equation for this problem using the symbols: m1, v1i, v1f, m2, v2i, and v2f 2.) Write the conservation of energy equation for this problem using the symbols: m1, v1i, v1f, m2, v2i, and v2f 3.) What is the gravitational potential energy of sphere 1 before it is released (use h = 0.0 cm as your reference point for gravity)? 4.) What is the velocity (v1f) of sphere 1 just after the collision? 5.) What is the velocity (v2f) of sphere 2 just after the collision?
