Question

A billiard ball rolling across a table at 1.55 m/s makes a head-on elastic collision with an identical ball. Find the velocity of each ball after the collision when each of the following occurs. (a) The second ball is initially at rest. 1st ball 2nd ball [ ] m/s (b) The second ball is moving toward the first at a speed of 1.05 m/s. m/s m/s 1st ball 2nd ball (c) The second ball is moving away from the first at a speed of 1.00 m/s. 1st ball m/s m/s 4. -/2 points A 86 kg fullback moving east with a speed of 6.0 m/s is tackled by a 97 kg opponent running north at 2.0 m/s. If the collision is perfectly inelastic, calculate each of the following. (a) the velocity of the players just after the tackle m/s (b) the kinetic energy lost as a result of the collision .-/1 pointsSerEssen1 6.P.041.son A 2000 kg car moving east at 10.0 m/s collides with a 3000 kg car moving north. The cars stick together and move as a unit after the collision, at an angle of 34.0° north of east and at a speed of 4.82 m/s. Find the speed of the 3000 kg car before the collision. m/s north

Explanation / Answer

When mass is same and collision is elastic then

velcities get exchanged.

(A) 1st : 0

2nd : - 1.55 m/s

(b) 1st : - 1.05 m/s

2nd : 1.55 m/s

(c) 1st : 1 m/s

2nd : 1.55 m/s
