marisa’s car accelerates at an average rate of 2.6 m/s2 calculate how long it takes her car to speed up from 24.6m/s to 26.8 m/s
To calculate the time it takes for Marisa's car to speed up from 24.6 m/s to 26.8 m/s, we can use the following equation:
v = u + at
where:
v = final velocity (26.8 m/s)
u = initial velocity (24.6 m/s)
a = acceleration (2.6 m/s²)
t = time
Rearranging the formula to solve for time (t), we have:
t = (v - u) / a
Substituting the given values into the formula:
t = (26.8 - 24.6) / 2.6
Simplifying the equation further:
t = 2.2 / 2.6
t ≈ 0.846 seconds
Therefore, it takes approximately 0.846 seconds for Marisa's car to speed up from 24.6 m/s to 26.8 m/s.
