Question

1. A cyclist accelerates uniformly from rest at point A and reaches point Y at a velocity of 9 m/s. The cyclist covers the last 10 m of her ride in 2 s. Determine the acceleration of the cyclist?

Answer 1

4 m/s^2 is the acceleration of the cyclist.

Explanation:

Given that,

Initial Velocity u = 0

v = 9 m/s

s = 10 m

As we know,

$v^2 - u^2 = 2as$

Thus,

$(9)^2 - (0)^2 = 2 * a * 10$

81 = 20a

a = 81/20

∵ a = 4.05 $m/s^2$ or 4 $m/s^2$
