PROBLEM FUUR (20 FUL ) A 420 kg car moving at 14.4 m/s hits from behind...
A 623 kg car moving at 18.2 m/s in the +x direction hits from behind a second car moving at 10 m/s in the same direction. If the second car has a mass of 593 kg and a speed of 19 m/s right after the collision, what is the velocity of the first car after this sudden collision? Please show work and explain. a) 26.8 m/s b) 8.74 m/s c) -9.63 m/s d) 9.63 m/s
A car with a mass 1078 kg and moving at a speed 5 m/s hits a motionless truck of mass 2998 kg whose brake is not engaged. If the car comes to a complete stop during the collision, how fast does the truck start moving?
10. A 2.0 kg ball moving with a speed of 3.0 m/s hits, elastically, an identical stationary ball as shown. If the first ball moves away with angle 30 Degree to the original path, determine a. the speed of the first ball after the collision. b. the speed and direction of the second ball after the collision.
A) If a 1552 kg car, moving at 8 m/s north, hits and sticks to a 1812 kg truck, moving at 6 m/s east, find the magnitude of the final speed. B) If a 1919 kg car, moving at 8 m/s north, hits and sticks to a 3187 kg truck, moving at 4 m/s west, find the direction of the final speed.
A railroad car of mass 3.25e4 kg is moving at 3.25 m/s collides and couples with two couples railroad cars, each of the same mass as the single car and moving in the same direction at 1.20m/s. A) what is the speed of the three coupled cars after the collision? B) how much kinetic energy is lost in the collision?
A
1000kg car moving at 15m/s to the right collided head-on with
another 1500 kg car who was coming in the opposite direction at a
speed of 20m/s. After collision the two cars interlocked to each
other, and the wreckage dragged with a new speed. What is the lost
of kinetic energy during the collision ?
A 1000 kg moving at 15 m/s to the right collided head-on with another 1500 kg car who was coming in the opposite direction...
A railroad car with a mass of 1.95 ✕ 104 kg moving at 2.88 m/s joins with two railroad cars already joined together, each with the same mass as the single car and initially moving in the same direction at 1.56 m/s. (a) What is the speed of the three joined cars after the collision? m/s (b) What is the decrease in kinetic energy during the collision? J
A railroad car of mass 3.10 ✕ 104 kg moving at 3.40 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? (b) How much kinetic energy is lost in the collision?
A railroad car of mass 3.15 ✕ 104 kg moving at 2.75 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? (b) How much kinetic energy is lost in the collision?
A 1100-kg car is moving at 20 m/s due north. A 1600-kg car is moving at 19 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. Determine the speed and direction of the combined two-car wreck immediately after the collision. magnitude=? direction=?
