A 5000 kg freight car rolls to the right and collides with a 10,000 kg freight car sitting at rest on the track. The cars connect as they collide and move to the right together at a speed of 2 m/s. What was the initial speed of the 5000 kg car? [Neglect friction]

Step 1
Given: Mass of the first car (m1) = 5000 kg Mass of the second car (m2) = 10000 kg Total mass (M) = m1 + m2 Total mass (M) = 5000 kg + 10000 kg Total mass (M) = 15000 kg Show more…

A $2000-\mathrm{kg}$ car moving east at $10.0 \mathrm{~m} / \mathrm{s}$ collides with a $3000-\mathrm{kg}$ car moving north. The cars stick together and move as a unit after the collision, at an angle of $40.0^{\circ}$ north of east and a speed of $5.22 \mathrm{~m} / \mathrm{s}$. Find the speed of the $3000-\mathrm{kg}$ car before the collision.
