A car traveling initially at 7.49 m/s acceler-
ates at the rate of 0.743 m/s2 for 5.41 s.
What is its velocity at the end of the accel-
eration?
To find the velocity of the car at the end of the acceleration, we can use the kinematic equation:
v = u + at
Where:
v = final velocity
u = initial velocity
a = acceleration
t = time
Given:
Initial velocity (u) = 7.49 m/s
Acceleration (a) = 0.743 m/s^2
Time (t) = 5.41 s
Substituting the values into the equation:
v = 7.49 m/s + (0.743 m/s^2)(5.41 s)
Now we can calculate it:
v = 7.49 m/s + 4.01963 m/s
v = 11.50963 m/s
Therefore, the velocity of the car at the end of the acceleration is 11.50963 m/s.
