- A 4900 kg open train car is rolling on frictionless rails at 18.6 m/s when it starts pouring rain. A few minutes later the car's speed is 15.4 m/s. What mass of water (in kg) has collected in the car?A block of mass m1 = 2 kg and speed v1 = 0.40 m/s collides with a block of mass m2 = 5 kg that is initially at rest. If the two blocks stick together, what is their speed right after the collision?Two 1.9 kg bodies, A and B, collide. The velocities before the collision are v A= (14î + 34 j) m/s and v = (-15î + 9.0j) m/s. After the collision, v = (-7.oî + 16 j) m/s. (a) What is the final velocity of B? m/s (b) What is the change in the total kinetic energy (including sign)? 121.69 J The net external force on the two particle system is zero; thus, the net momentum of the system cannot change. The net momentum along the x axis before the collision must equal that after the collision. Same for the y axis. Use the definition of kinetic energy to find the total K before the collision and the total K after.
