A bicycler rider is traveling at 7m/s. During an 8s period, the bicycle rider then slows down with acceleration to a speed of 3 m/s. How far does the bicycle rider travel during the 8s?

d=7m/s
s=3m/s
t=8s

t x s = d/t x t
d = s x t

1 answer

Vo = 7 m/s
V = 3 m/s
t = 8 s.

V = Vo + a*t
Solve for a. It should be negative.

d = Vo*t + 0.5a*t^2
Solve for d.
