Question
A mountain biker is initially traveling at 8.3 m/s, they see a snake on the
15 points
trail in front of them and brake at 3.1 m/s2 to avoid running over the
snake. How long does it take them to stop? The snake is 10 m away when
they see it, do they stop in time?
v = 8.3 m/s
Acceleration: - 3.1 m/s?
d = ?
10 m
v = 8.3 m/s
V = ?
Acceleration: - 3.1 m/s?
d = 10 m
t = 2.115 sec
t= 1.651 sec
t = 1.013 sec
t = 2. 021 sec
