A 3000-Kg car moving east at 10m/s collides with a 5000-kg car moving north. The car's stick together and move as a unit after a collision, at an angle of 45 degree north of east and a speed of 5 m/s. Find the speed of 5000 kg car before collision. (Ans: V_iy = 5.66m/s)
2. At an intersection a 1500 Kg car, moving east at 30 m/s collides with and sticks to a 2500 Kg van that is initially going north at 20 m/s. find the velocity of the wreckage immediately after the collision.
An 8.57 kg mass moving east at 14.1 m/s on a frictionless horizontal surface collides with a 10.9 kg mass that is initially at rest. After the collision, the 8.57 kg mass moves south at 2.50 m/s. What is the magnitude of the velocity of the 10.9 kg mass after the collision? Tries 0/8 Submit Answer What is the angle relative to the east? Submit Answer Tries 0/8 What percentage of the initial kinetic energy is lost in the collision?...

Jack is sliding due east on the surface of a frozen pond. He collides with Jill, who is initially at rest. After the collision, Jack is sliding 30.0◦ south of east, at 2/3 of his initial speed. Jill is 3/4 as massive as Jack. What angle is Jill moving at after the collision?
Particle A is at rest, and particle B collides head-on with it. The collision is completely inelastic, so the two particles stick together after the collision and move off with a common velocity. The masses of the particles are different, and no external forces act on them. The de Broglie wavelength of particle B before the collision is 1.8 × 10-34 m. What is the de Broglie wavelength of the object that moves off after the collision?
A 1000kg automobile moving with a speed of 24 m/s collides with a 500kg car initially at rest. If the two stick together, what is the velocity (in m/s) of the two cars after the collision relative to an automobile moving in the same direction at 15 m/s?
A neutron collides elastically with a helium nucleus (at rest initially) whose mass is four times that of the neutron. The helium nucleus is observed to move off at an angle θ′2=45∘. The neutron's initial speed is 6.0×105 m/s . Determine the angle of the neutron, θ′1, after the collision. Determine the speeds of the two particles, v′n and v′He, after the collision
A 0.25kg ball moving toward the east on a frictionless table at 3.0m/s collides elastically with a 0.40kg ball that is at rest. All we know about the balls after the collision is that the 0.40kg ball moves at 30degrees south of east. Set up but do not solve the equations that can be used to find the speeds of both balls and direction of the first ball after the collision.
On an icy road, a 1600-kg car moving north at 23 m/s collides with a 2400-kg car moving east at 16 m/s. The two cars stick and move together. Let east be the x direction, and north be the y direction. What is the y-component of the velocity of the wreckage after the collision?
