Q.20. As given in the figure, the surface is friction less. The two objects collide, stick together and move together after the collision. Find the magnitude of final velocity in m/s? (write numerical value only) m, =3Kg m = +kg Vq =!Omls v =8m/s

A 1000kg car traveling east at 30mi/hr collides with a 2000kg truck traveling west at 30 mi/hr. The two vehicles stick together. What is the veloicity of the wreck just after the collision?

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.

given a random scenario a proton with at0m mass 1.00 has speed of 500m/s collide with another proton at rest. and the collided elastically! the original proton went 56 degree from the initial direction 0f the travel. FIND: 1. what is the direction of the velocity of 2nd pr0ton after they collided 2. what is the final speed of the tw0 pr0tons after they collided?

A 1500-kg car moving at 6 m/s collides with a 3500-kg truck at 1 m/s in the opposite direction. The car and truck are both rolling in neutral without friction. They stick together and continue rolling after the collision. What is the final velocity of the joined pair and what is the fraction of energy lost during the collision, (Ki-Kf)/Ki?

1. a) For a particle of mass m and velocity v, what are the momentum, and its (kinetic) energy? b) Discuss the principles of Conservation of Momentum and Conservation of Energy. Use the collision between two particles as an example.

Q.12. Consider two particles of masses m, = m and m2 = 3m moving with initial velocities Vii +1 m/s and v2i = -1 m/s along the same direction. The two %3D particles collide head-on elastically, and then leave the collision site with different velocities, v1f and var. The final velocities immediately after collision are: a. Vif = -2 m/s; v2f = 0 m/s %3D b. Vif = 0 m/s; V2f = 0.5 m/s c. Vif = -2.5 m/s; v2r = 0.5 m/s 3 m d. Vif = -4 m/s; v2f = 0 m/s

In an Atwoods Machine lab with m1 = 0.1 and m2 = 0.13 observed acceleration is 1.20 m/s^2. Compare the value with the a(theoretical).   During the momentum collision lab a 2.5kg mass moving with 2m/s hits a stationary 5kg mass. After the collision 2.5kg bounces back with 0.5m/s and 5kg mass moves with 1.2 m/s. Calculate Pi and Pf and compare using percent error. Does this experiment show conservation of momentum?
