Question

Part A: When their centers are a distance 30.0 m apart, find the speed of the 21.0 kg sphere.

    v1=___m/s

Part B: Find the speed of the sphere with mass 100.0 kg .

       v2=___m/s

Part C: Find the magnitude of the relative velocity with which one sphere is approaching to the other.

     vr=___m/s

Part D: How far from the initial position of the center of the 21.0 kg sphere do the surfaces of the two spheres collide?

     L=___m 

 
An experiment is performed in deep space with two
uniform spheres, one with mass 21.0 kg and the
other with mass 100.0 kg . They have equal radii, r
= 0.15 m. The spheres are released from rest with
their centers a distance 45.0 m apart. They
accelerate toward each other because of their
mutual gravitational attraction. You can ignore all
gravitational forces other than that between the two
spheres.
