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.
17) A 7700 kg boxcar traveling at 14.0 m/s strikes a second car at rest. The two stick together and move off with a speed of 5.0 m/s. What is the mass of the second car? A) 14000 kg B) 13000 kg C) 13860 kg D) 13720 kg E) 12970 kg
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
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.
A6.0 kg disk traveling at 9.0 m/s strikes a 7.0 kg stick of length 5.0 m that is lying flat on nearly frictionless ice as shown in the overhead view in the figure below. The disk strikes at the endpoint of the stick, at a distance r = 2.5 m from the stick's center. Suppose that the collision is perfectly inelastic so that the disk adheres to the stick at the endpoint at which it strikes. The moment of inertia...
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.
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...
with good explanation. 2. A6.0 kg disk traveling at 9.0 m/s strikes a 7.0 kg stick of length 5.0 m that is lying flat on nearly frictionless ice as shown in the overhead view in the figure below. The disk strikes at the endpoint of the stick at a distance r 2.5 m from the stick's center. Suppose that the collision is perfectly inelastic so that the disk adheres to the stick at the endpoint at which it strikes. The...
The Boxcar 1 moves to the right at speed v1 = 5.4 m/s. After collision, the three boxcars latch together and move off together as one mass, with speed vnew to the right. The new speed vnew is... LE! 1 3 Diagram is snapshot before collision. Mass of each boxcar = 10,000 kg.
