Suppose you are traveling in a bus that has a mass of 125kg at a highway speed of 45km/s for 10s on a nice summer day and the momentum, 250kg. m/s, of an unlucky bug with a mass of 25kg is suddenly changed as it splatters onto the front window.
This is NOT a multiple-choice question Answer all questions (1-4)
1.
Compared to the force that acts on the bug, how much force acts on the bus? (Find the speed of both the
you need acceleration!) F-MA
bus and bug. Remember:
2.
Although the momentum of the bus is very large compared to the momentum of the bug, explain the change
compared to the change in momentum of the bug.
in momentum of the bus
3.
Which of the two experiences the greater acceleration
4.
Which, therefore, would suffer the greater damage and why?
I
