A projectile proton with a speed of 1500 m/s collides elastically with a target proton initially at rest. The two protons then move along perpendicular paths, with the projectile path at 72° from the original direction. After the collision, what are the speeds of (a) the target proton and (b) the projectile proton?

A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision.   a)what are is the magnitude of the velocity of the two vehicles just after the collision?

A 500-gram ball traveling to the right at 4.0 m/s collides with and bounces off another ball that is initially at rest. The figure shows the momentum vector of the first ball after the collision. Draw (a) the momentum vector of the first ball before the collision and (b) the momentum vector of the second ball after the collision.

Lucy is cruising through space in her new spaceship. As she coasts along, a tiny spacebug drifts into her path and bounces off the window. Consider several statements concerning this scenario. Evaluate each statement according to the law of momentum conservation and match it to the appropriate category. Must be true according to the law of momentum conservation Must be false according to the law of momentum conservation Answer Bank Not determined by the law of momentum conservation If the spacebug had stuck to the spaceship instead of bouncing off, momentum would not have been conserved for this interaction. The change in the spacebug's momentum during the collision is greater than the change in the spaceship's momentum. The total chanaa in momentum for this interaction is nem The total momentum of the spaceship and spacebug before the collision is equal to their total momentum afterward. 日示全部 X

A radioactive nucleus at rest decays into a second nucleus, an electron, and a neutrino. The electron and neutrino are emitted at right angles and have momenta of Pe=9.67x10-23 kg. m/s and p = 5.99×10-23 kg. m/s. respectively.

A ball struck by a bat experiences a change in momentum of 42 kg m/s . If the time of interaction is 0.29 s, what is the magnitude of the average force acting on the ball (in N) ?

Answer part a, b and c

this is a multi step problem but I am just having trouble with this part of the problem. Here are the values that I correctly calculated: mass of particle 1=6 kg initial velocity for particle 1= 185i+138j final velocity for particle 1= -68.89i+-50.67j F21=-15.9e-t/96i+-100sin(2πt/96)j I am trying to find: What is the x displacement for particle 1? I think that I need to use Newtons second law to get an expression for acceleration, and then integrate but I am not getting the right answers.

A 1 kg mass moves on a horizontal surface and collides with a 2 kg mass, initially at rest.  The masses stick together and move as a single mass.  the velocity of the system after the collision is ________ the velocity of the 1 kg mass before the collision
