Two asteroids collide and stick together. The first asteroid has mass of 15×103kg and is initially moving at 770 m/s. The second asteroid has mass of 20×103kg and is moving at 1020 m/s. Their initial velocities made an angle of 20° with respect to each other. What is the final speed and direction with respect to the velocity of the first asteroid?

After the collision, the orange ball always goes off in the positive x-direction.  The final speeds are v and V.  Calculate the angle θ that the green ball goes off in.  V0 = the initial green body's speed = 6 m/s M = the mass of both balls = 2 kg φ = the incoming green ball's angle = 60o

The following two questions relate to a baseball being hit. Just before the ball (of mass 0.4kg) contacts the bat, it is travelling in the negative x direction with a speed of 20m/s. Immediately after the hit, the ball moves away from the bat in the positive x direction with a speed of 30 m/s. The bat is in contact with the ball for 10 milli-seconds. 10. What is the magnitude of the average force on the ball in the x direction, while it is in contact with the bat? A) 400 N B) 1200 N C) 1600 N D) 2000 N E) 100,000 N 11. While in contact with the bat, there is an instant when the ball is stationary. At that instant, describe the acceleration of the ball in the x direction: A) In the positive x direction and non-zero B) In the negative x direction and non-zero C) Zero

Ball A has a mass of 3 kg and is moving with a velocity of (vA)1 = 9 m/s when it makes a direct collision with ball B, which has a mass of 2.5 kg and is moving with a velocity of (vB)1 = 5 m/s . Suppose that e = 0.7. Neglect the size of the balls. a) Determine the velocity of A just after the collision measured to the right. (vA)2 = ? b) Determine the velocity of B just after the collision measured to the right. (vB)2 = ?
