## Homework Statement

Gaetan Boucher started from rest and skated around a circular ice track of radius 100m. He maintained a constant rate of increase of his speed and finished one complete lap in 30s. Calculate the magnitude of his total acceleration as he passed a point 1/4 of the distance around the track from the start.

## The Attempt at a Solution

v1 = 0m/s

r = 100m

d = 1/4d

a = ?

t = 30s

c = 1/4 x 2rπ

c = 157 m

t = 1/4 (30s)

t = 7.5s

157 m = (0m/s + v2)/2 (7.5s)

41.866 m/s = v2

157 m = 1/2a(t)2

5.58 m/s^2 = a
