Answer:
98 m √
Explanation:
How about s = Vo * t + ½at² ?
s = h = Vo * 2s - 4.9m/s² * (2s)² = 2Vo - 19.6
and
h = Vo * 10s - 4.9m/s² * (10s)² = 10Vo - 490
Subtract 2nd from first:
0 = -8Vo + 470.4
Vo = 58.8 m/s
h = 58.8m/s * 2s - 4.9m/s² * (2s)² = 98 m
The acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².
<h3>How to calculate acceleration?</h3>
The acceleration of a moving object can be calculated using the following formula:
a = (v - u)/t
Where;
- a = acceleration (m/s²)
- v = final velocity (m/s)
- u = initial velocity (m/s)
- t = time (s)
According to this question, a car starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds.
a = (25.5 - 12.5)/5
a = 13.0/5
a = 2.6m/s²
Therefore, the acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².

Answer:
62.5 miles per hour
Explanation:
Speed = Distance travelled / Time taken
Speed = 125/2 = 62.5
You derive the units of the speed...by using the speed formula....,
Speed = Distance/Time
Speed = miles/hour
Hence the units for the speed = miles/hour
Answer: The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
