A 6800-kg boxcar traveling at 16 m/s strikes a second boxcar at rest. The two stick together and move off with a speed of 5.5 m/s What is the mass of the second car?
A 9300 kg boxcar traveling at 15.0 m/s strikes a second boxcar at rest. The two stick together and move off with a speed of 6.0 m/s. What is the mass of the second car? Calculate the amount of kinetic energy lost as thermal energy during the collision.
A 7400-kg boxcar traveling at 16 m/s strikes a second boxcar at rest. The two stick together and move off with a speed of 6.5 m/s .
An empty railroad car traveling at a speed of 21 m/s strikes a second car at rest. The second car, being with passengers has twice the mass of the first car if the cars lock together as a result of the collision their common speed afterward is 11 m/s. 10 m/s. 9.0 m/s. 8.0 m/s. 7.0 m/s.
023 10.0 points A car with mass 1358 kg, moving at 31 m/s, strikes a(n) 2897 kg car at rest. If the two cars stick together, with what speed do they move? Answer in units of m/s.
A 2,000 kg car traveling north at a velocity of 45m/s strikes 2,200 Kg car traveling west at 50 m/s. The two vehicles strike each other and stick together. As a single combined mass they slide across the pavement which has a coefficient of kinetic friction 0.07. What is the displacement from the point of impact to the final resting place of the cars? (How long does it take for them to come to rest?) A 200 Kg ball is...
A boxcar traveling at 10 m/s approaches a string of 2 identical boxcars sitting stationary on the track. The moving boxcar collides and links with the stationary cars and they all move off together along the track. What is the final speed of the cars immediately after the collision? (You may take the mass of each boxcar to be 18,537 kg.) m/s
A 1890 kg car traveling at 13.3 m/s collides with a 2970 kg car that is initally at rest at a stoplight. The cars stick together and move 1.96 m before friction causes them to stop. Determine the coefficient of kinetic friction between the cars and the road, assuming that the negative acceleration is constant and all wheels on both cars lock at the time of impact. A 1890 kg car traveling at 13.3 m/s collides with a 2970 kg...
12. A 1500-kg car traveling at 30 m/s east collides with a 3000-kg car traveling at 20 m/s south. The two cars stick together after the collision. What is the speed of the cars after 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.
