Impulse and Momentum Problem Solving 30. A 1-kg ball (m,) is moving with a velocity of (10 m/s)i makes an elastic collision with an identical ball (m,) moving with a velocity of (5 m/s)j. The velocity of m, after collision is 8 m/s, 30° N of E. What is the velocity of m, after collision? 31. Two cars collided at an intersection. Car 1 has a mass of 1460 kg with a velocity of 75 km/h going West. Car 2 has a mass of 1190 kg with a velocity of 100 km/h going North. After collision, the two cars stick together and moved at an angle e from the horizontal. Find the value of e and the final velocity of the two cars.
