Question

Physics: In a certain region of space, a force F(r) has an associated potential energy of the form U(r) = a r2 − b r + c , where a , b , and c are positive constants. What are the points, if any, where the force F(r) goes to zero?

Drreeaa · Accepted Answer

Yes, the law of conservation of momentum is satisfied. The total momentum before the collision is 1.5 kg • m/s, and the total momentum after the collision is
1.5 kg • m/s. The momentum stays the same after the collision.
