An 87.0 kg sprinter starts a race with an acceleration of 2.28 m/s^2. If the sprinter accelerates at that rate for 30 m, and then maintains that velocity for the remainder of the 100 m dash, what will be his time (in s) for the race?
Added by Santiago M.
Step 1
We can use the formula for acceleration, which is final velocity = initial velocity + acceleration * time. Since the sprinter starts from rest, his initial velocity is 0. So, we can rearrange the formula to solve for time: time = final velocity / Show more…

A 75.0 kg sprinter starts a race with an acceleration of 1.80 m/s2. If the sprinter accelerates at that rate for 13 m, and then maintains that velocity for the remainder of the 100 m dash, what will be his time (in s) for the race?

An 89.0 kg sprinter starts a race with an acceleration of 1.32 m/s2. If the sprinter accelerates at that rate for 36 m, and then maintains that velocity for the remainder of the 100 m dash, what will be his time (in s) for the race?

A runner of mass 56.1 kg starts from rest and accelerates with a constant acceleration of $1.23 \mathrm{~m} / \mathrm{s}^{2}$ until she reaches a velocity of $5.10 \mathrm{~m} / \mathrm{s}$. She then continues running at this constant velocity. How long does the runner take to travel $173 \mathrm{~m} ?$
