Two toy trucks, travelling towards each other, collide. Just before the collision, the 1st truck of mass m1= 2 kg travelled to the right with speed 5 m/s, and 2nd truck of mass m2=8 kg travelled to the left with speed 5 m/s. Right after the collision, the 1st truck bounces back with speed 18 m/s. What is the final speed of the 2nd truck?

A car of mass m 2000.0kg is moving at speed vi25.0 m/s towards East. A truck of mass m2 6000.0kg is moving at speed v2i-10.0m/s towards North. They collide at an m1- intersection and get entangled (complete inelastic collision). 1. What is the magnitude and direction of the final velocity of the entangled automobiles? 2. How much kinetic energy is lost in the collision. That is, calculate the change in the kinetic energy of the system
Consider two masses sliding across a frictionless surface about to undergo a head-on collision as shown in the figure. The first mass (m1 = 3 kg) is travelling to the right with a speed of V1 = 8 m/s. The speed of the second mass (m2 = 5 kg) is unknown. After the masses collide, m1 rebounds moving off at a speed of v = 2 m/s in the opposite direction, while m2 is motionless. a)(10 pts.) At what velocity,...
Two objects collide head-on (see figure below). The first object is moving with an initial speed of 7.99 m/s to the right and the second object is moving with an initial speed of 10.00 m/s to the left. Assuming the collision is elastic, m1 = 5.12 kg and m2 = 6.15 kg,determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left.) v1f =...

6. Two football players run towards each other and collide on a slick, muddy field. Assuming that player A has mass of 85 kg and speed of 7 m/s and player B has mass of 75 kg and speed of 7.5 m/s, what happens right after they collide (and stick together)? 8.

. Two trucks of equal mass collide at a 90degree intersection. If the momentum of truck A is 9.50 x 10^4 kg km/h east and the momentum of truck B is 1.05 x 10^5 kg km/h north, what is the resulting momentum of the final mass, assuming the trucks remain joined together following the crash?
inelastic collision in a accident two cars travelling in opposite directions collide and stick together. the first car had a mass of 1000 kg and a speed of 20m/s, the second had a mass of 1750 kg and a speed of -15m/s. what is the speed of the two cars immediately after the crash?
Two objects collide head-on (see figure below). The first object is moving with an initial speed of v1i = 8.06 m/s and the second object is moving with an initial speed of v2i = 10.00 m/s. Assuming the collision is elastic, m1 = 5.24 kg, and m2 = 6.30 kg, determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the...
physics-- two cars with the mass of 300 kg (each) move towards eachother, collide head on and get joined together. before the collision: car 1 is traveling at 41 m/s and car 2 is traveling at 65 m/s. what is their speed immediately after the collision?
just need d and e. thank you 6. Consider a head-on collision between two pucks, T = 0.5 kg and m = 0.3 kg in the image below. V2 The puck m, is initially travelling in the +x direction with velocity o, = +10m/s, and m, is initially travelling in the x direction with velocity = -3m/s. The two collide with a perfectly elastic collision along the x-direction. (a) What is the speed of the center of mass of the...
