Question

A bobsled finishes a race traveling at 32 m/s. After braking the sled slows with an acceleration of -2m/s^2.

How long does it take for the bobsled to stop?

How far does the bobsled travel in the time it takes to stop?

Answer 1

Answer #1

a)
t= v/a
t = 32/2
t = 16 sec .

b) d = vt + 0.5*a*t²
d= 32x16 - 16²
d= 256 m .

You are traveling at 50 mph (22 m/s) when you see that far ahead traffic has come to a stop. You press on the brake causing an acceleration (deceleration) of -3.3 m/s^2 until you come to a stop. How much time does it take to come to a stop after you began braking? (answer to the nearest 0.1 second, giving the numerical value without units)
