a car traveling at 7.0 m/s accelerates uniformly at 2.5 m/s TO REACH A SPEED OF 12.0 M/S
HOW LONG DOES IT TAKE FOR THIS ACCELERATION TO OCCUR?
vfinal=vinitial+ a*time
solve for time.
To determine how long it takes for the acceleration to occur, we can use the formula:
v = u + at
where:
v = final velocity (12.0 m/s)
u = initial velocity (7.0 m/s)
a = acceleration (2.5 m/s^2)
t = time
First, let's rearrange the formula to solve for time:
t = (v - u) / a
Plugging in the values:
t = (12.0 m/s - 7.0 m/s) / 2.5 m/s^2
Simplifying:
t = 5.0 m/s / 2.5 m/s^2
t = 2.0 seconds
Therefore, it takes 2.0 seconds for the acceleration to occur.
