1)
When a cannon fires a cannon ball, the cannon will recoil backward because
energy of cannon and cannon ball is conserved
momentum of the cannon is greater than energy of the cannon ball
momentum of the cannon ball and cannon is conserved
energy of the cannon is greater than the energy of cannon ball
2)
Two equal mass objects A and B collide elastically while travelling in opposite directions with same speed. After the collision, there velocities are
zero
interchanged
unchanged
Both are reduced in magnitude
3)
A very heavy object moving with velocity v collides head-on with a very light object moving with velocity -v. The collision is elastic, and there is no friction. The heavy object barely slows down. What is the speed of the light object after the collision?
nearly v
nearly 3v
nearly infinite
nearly 2v
4)
Two cars collide in a completely inelastic collision at a North-South East-West intersection. The skid marks point roughly northwest. Concerning the initial directions of the two cars, this tells you that one driver was traveling:
West: the other driver was travelling the south
East:the other driver was travelling the south
West: the other driver was travelling the north
East:the other driver was travelling the north
5)
A rubber ball with a speed of 5.0 m/s collides head-on elastically with an identical ball at rest. What is the speed of the initially stopped ball after the collision?
1.0 m/s
2.5 m/s
5.0 m/s
zero
