During a race, a sprinter accelerated 1.8 m/s 2 in 2.5 seconds. The sprint increase with this amount of acceleration by 4.5 m/s.
<h3>What is acceleration?</h3>
Acceleration is the time rate of change of velocity.
Acceleration a = velocity v / time t
1.8 = v/2.5
v = 4.5 m/s
The sprint increase with this amount of acceleration by 4.5 m/s.

Answer:
Lens
Explanation:
Lenses fit this description.
t = 0.527 s
<u>It accelerates for 0.527 s.</u>
<u>Explanation:</u>
We use the formula:
v = u+at
Given:
v = 106 m/s
u = 0 (since no gravity)
So applying the formula,
v = u+at
106 = 0 + 201t
t = 106/201
t = 0.527 s
You would expect to find the center of gravity in a ruler in the middle because if you were to cut a ruler in half, depending on the center of gravity, you would have two equal pieces, which mean there is equal weight, meaning the middle is the center of gravity
<span>Spring tides have higher high tides and lower low tides when the moon, sun, and earth are aligned in a row. Why does this occur?
A.gravitational pull is stronger
