**Raghav**, Monday, February 20, 2012 at 12:15amThe driver of a speeding empty truck (initial speed of Vi) slams on the brakes and skids to a stop through a distance d. Assuming that the brakes always supply the same stopping force, consider the following situations:

1

(a) If the truck carried a load that doubled its mass, what would be the

truck’s “skidding distance” in terms of d?

2d

d

d/2

d/4

2

(b) If the initial speed (with its initial mass) of the truck were halved, what would be the truck’s “skidding distance” in terms of d?

2d

d

d/2

d/4

3

(c) If the stopping distance is now 4d, what is the initial velocity (Vi) of the truck?

2Vi

Vi

Vi/2

Vi/4
