While driving his sports car at 20.0 down a four lane highway Eddie comes up behind a slow-moving dump truck abd decides to pass it in the left lane. If Eddie can accelerate at 5.00 m/s^2, how long will it take for him to reach a speed of 30.0 m/s?
Dont knoe
A= change of velocity/change over time
you don't know time
change of velocity/acceleration=time
10 m/s / 5m/s^2 = 2s
To find the time it takes for Eddie to reach a speed of 30.0 m/s, we can use the formula for acceleration:
v = u + at
where:
v = final velocity (30.0 m/s)
u = initial velocity (20.0 m/s)
a = acceleration (5.00 m/s^2)
t = time
We need to rearrange the formula to solve for time (t):
t = (v - u) / a
Substituting the given values into the formula:
t = (30.0 m/s - 20.0 m/s) / 5.00 m/s^2
Now we can calculate the time it takes for Eddie to reach a speed of 30.0 m/s:
t = 10.0 m/s / 5.00 m/s^2
t = 2.00 s
Therefore, it will take Eddie 2.00 seconds to reach a speed of 30.0 m/s.
