024 10.0 points of mass 2000 kg, are moving at right angles to each other when they collide and stick to- gether. The initial velocity of the first car is 11 m/s in the positive r direction and that of the second car is 16 m/s in the positive g directionn What is the magnitude of the velocity of the wreckage of the two cars immediately after the collision? 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...
