A 1200 kg car traveling 45.0o south of east at 18.0 m/s collides with a 850 kg car traveling north at 23.0 m/s. The cars stick together. What is the velocity of the wreckage just after the collision?
A 900 Kg car is traveling east at 15 m/s when it collides with a 750 Kg car traveling north at 20 m/s. The cars stick together. What is the kinetic energy of the system after the collision?
A 900-kg car traveling east at 15.0 m/s collides with a 750-kg car traveling north at 20.0 m/s. The cars stick together. Assume that any other unbalanced forces are negligible. a. What is the speed of the wreckage just after the collision? b. In what direction does the wreckage move just after the collision? c. How much kinetic energy is lost in this collision.
A 900 kg car traveling east at 15.0 m/s suddenly collides with a 750 kg car traveling north at 20.0 m/s. The cars stick together after the collision. What is the velocity of the wreckage move just after the collision?
A car with mass 1500 kg traveling east at 25 m/s collides at an intersection with a 2500kg van traveling north at a speed of 20 m/s. Find the magnitude and direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision and assuming no friction.
A 900 kg car is traveling at 15 m/s when it suddenly collides with a 750 kg car traveling north at 20 m/s. The cars stick together after the collision. What is the speed of the wreckage just after the collision?
A 1500-kg car traveling east at 50 m/s collides with a 2200-kg truck traveling north at 66 m/s. The car and truck become entangled and slide to a stop. What is the final speed immediately after the collision? What angle with respect to the east direction do the entangled vehicles slide?
A 3000-Kg car moving east at 10m/s collides with a 5000-kg car moving north. The car's stick together and move as a unit after a collision, at an angle of 45 degree north of east and a speed of 5 m/s. Find the speed of 5000 kg car before collision. (Ans: V_iy = 5.66m/s)
a car of mass 1500 kg traveling northward at 16m/s collides in an intersection with a 1700 kg car traveling at 12 m/s in a direction 30 degrees north of east. (a) assuming that the two cars become stuck, find the velocity of the wreck immediately after the collision. (b) calculate the average force on a 100kg passenger in the first car. duration of collision: change in t=50 ms
A 1500 kg aircraft going 30 m/s collides with a 3000 kg aircraft that is parked and they stick together after the collision and are going 10 m/s after the collision. If they skid for 117.7 m before stopping, how long (in seconds) did they skid? Hint: Are the aircraft moving at a constant velocity after the collision or do they experience an acceleration?
