A 15800 kg semi truck sliding on ice with velocity V₁-11.00 rear-ends a sedan of 1600 kg also sliding in the same direction with velocity v2=5.00m. Assume they bounce off each other in a one- dimensional perfectly elastic collision. V1i What is the velocity (V₁) of the semi truck after the collision? m What is the velocity (V2r) of the sedan after the collision? m Is energy lost during the collision? O Cannot tell with information provided O Yes O No V2i +

A simple pendelum made of a pendelum bob of mass, m1=.0250 kg, and a string of length, l= .720m, is pulled back to an angle of theta = 35 degrees and then released from rest. At the bottom of the swing m1 and m2=.0200 kg collide and stick together. a. What is the speed of m1 immediately before it hits m2? b. What is the speed of m2 immediately after the collision? c. How high above the bottom of the swing do the two masses rise?

a block with a mass of 0.5 kg is released from rest on a frictionless track at a distance 2.5m above the top of the table. it then collides elastically with an object having mass m2=1.0kg that is initially at rest on the table as shown in the figure. the table is h2=2.oo m . a)How far away from the bottom of the table do the objects land ? Hints : determine the velocities just after the collision . how high does object 1 travel back up the track. b) suppose the collision is inelastic , where does combined object land   please see attached image

I.  A lump of clay (m = 3.01 kg) is thrown towards a wall at speed v = 3.15 m/s.  The lump sticks to the wall.  (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   II.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.15 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   III.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.24 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic…

A railroad car of mass 2.45 × 10* kg moving at 2.65 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? m/s (b) How much kinetic energy is lost in the collision? J
