A proton is travelling to the right at 2.0 × 10^7  m s. It has a head-on perfectly elastic collision with a stationary carbon atom. The mass of the carbon atom is 12 times the mass of the proton. What are the speed and direction of each after the collision?

A 92 kg boulder , moving at 5.0 m/s attempts to pass directly across the adit of a mine. Just as the boulder reaches the end of the adit, it was met head-on in midair by two 75 kg miners, both moving in the direction opposite the boulder. One is moving 2.0 m/s, the other at 3.0 m/s . They all become entangled as one mass. What is their velocity after the collision? 18. What is the momentum of a 18 kg object traveling at a constant velocity that has 295 J of kinetic energy?

Object 1 with a mass of 4.70 kg, moving right at a speed of 7.80 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.30 kg moving left at a speed of 10.6 m/s. After the collision, the Object 1 is moving left at 2.40 m/s. 10. What is true about the total momentum before and after the collision? O Equal in magnitude but opposite in direction O Different in magnitude and direction O Equal in magnitude and direction O Different in magnitude but in the same direction

Two pieces of space debris drift toward each other, collide, and stick together. The first piece has a mass of 45 kg and a velocity of m/s just before the collision. The second piece has a mass of 65 kg and a velocity of m/s just before the collision. What is the velocity of their center of mass after the collision? O ( 0.73, 0.73, 4.95 ) m/s O ( 3.27, 3.27, 4.05 ) m/s O ( 9.00, -5.00, 9.00 ) m/s O ( -0.99, -0.99, 11.50 ) m/s O None of the above

Need help checking a practice problem. Thanks!

A particle of mass m₁ and velocity v₁ hits the stationary particle of mass m2. After the collision, the outgoing speeds of these particles are equal. Considering elastic collision what is the angle between velocities of the particles after collision? Mass m₁ = 2m2.

In this problem, an astronaut is landes on the 6.1×1021 kg asteroid traveling at 9830 m/s and detonates a nuclear bomb. The asteroid breaks into two pieces of equal mass. One piece will fly off at an angle of 30∘ and speed 9700 m/s. What will be the speed and angle of the second piece?

You launch a 20 kg shell at 45 degrees and at a speed of 25 m/sec. 1 second after launching it, it explodes into two fragments. Note that the first fragment of 15 kg has a speed of 30 m/sec horizontally forward immediately after the explosion. What is the speed of the second fragment ?

Box 1 is sitting at rest. Box 2 is moving to the left when it collides with Box 1 (see figure). This time the two boxes stick together after the collision. The surface is frictionless. Take the right to be the positive x-direction.The mass of Box 1 is 3.80 kg. The mass of Box 2 is 5.60 kg. The speed of Box 2 is 1.20 m/s before the collision. The speed of the boxes together is 0.715 m/s after the collision.What is the total kinetic energy (both boxes) after the collision?
