A bicycle initially at rest uniformly accelerates at 2.0 m/s2 for 5 s. Determine the final velocity of the bicycle at the end of five seconds.
Question
A bicycle initially at rest uniformly accelerates at 2.0 m/s² for 5 s.
Determine the final velocity of the bicycle at the end of five seconds.
Solution
To solve this problem, we can use the formula for final velocity in uniformly accelerated motion, which is:
v = u + at
where: v = final velocity u = initial velocity a = acceleration t = time
Given in the problem: u = 0 (since the bicycle is initially at rest) a = 2.0 m/s² t = 5 s
Substituting these values into the formula, we get:
v = 0 + 2.0 m/s² * 5 s = 10 m/s
So, the final velocity of the bicycle at the end of five seconds is 10 m/s.
