Fill in the blank
Question 2
2.

Fill in the blank
Question 3
3.
Th recoil momentum of the cannon that kick is
Question 4
4.
Compared to the force that acts on the bug, how much force acts on the bus?
Question 5
5.
The time of impact is the same for both the bug and the bus. Compared to the impulse on the bug, this means the impulse on the bus is
Question 6
6.
Although the momentum of the bus is very large compared to the momentum of the bug, the change in momentum of the bus compared to the change in momentum of the bug is
Question 7
7.
Which undergoes the greater acceleration (change in speed and/or direction)?
