A 3.0 kg cart moving at 2 m/s. strikes a stationary 3.0 kg cart. If it is an elastic collision, what will be their final velocities ? Conservation of linear momentum: m_1V_1(b.c) + m_2V_2(b.c) = m_1V_1(a.c) + m_2V_2(a.c)
Suppose in a reference frame S, two objects collide elastically. Particle 1 of mass m1 = 2m is initally at rest, and particle 2 of mass m2 = m is moving with an initial velocity of u2i = −0.75c (negative means moving in the −x direction). The two particles collide elastically. Using classical momentum and energy conservation, an observer in frame S calculates the velocities after collision to be u1f = −0.5c, u2f = 0.25c. (a) Verify that the kinetic...
A 5 kg cart moving at a velocity 2 m/s in the +x-direction collides completely inelastically (i.e. they stick) with a second cart of mass 1.5 kg which is initially moving at a velocity of 10 m/s in the +y-direction.
