A car traveling at 7.3 m/s accelerates 4.5 m/s2 to reach a speed of 11.0 m/s.
How long does it take for this acceleration to occur?
Answer in units of s.
To find the time it takes for the acceleration to occur, we can use the equation:
v = u + at
Where:
v = final velocity (11.0 m/s)
u = initial velocity (7.3 m/s)
a = acceleration (4.5 m/s^2)
t = time
We can rearrange the equation to solve for time:
t = (v - u) / a
Substituting the given values, we have:
t = (11.0 m/s - 7.3 m/s) / 4.5 m/s^2
t = 3.7 m/s / 4.5 m/s^2
t ≈ 0.822 s
Therefore, it takes approximately 0.822 seconds for the acceleration to occur.
