A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial victory of 11.5m/s and accelerates at the rate of 0.500 m/s^2 for 7.00s. (a) What is his final velocity?
To find the final velocity of the racer, we can use the equation for accelerated motion:
Vf = Vi + at
Where:
Vf = final velocity
Vi = initial velocity
a = acceleration
t = time
Given that:
Vi = 11.5 m/s
a = 0.500 m/s^2
t = 7.00 s
Substituting the values into the equation, we have:
Vf = 11.5 m/s + (0.500 m/s^2)(7.00 s)
Vf = 11.5 m/s + 3.5 m/s
Vf = 15.0 m/s
Therefore, the racer's final velocity is 15.0 m/s.
To find the final velocity of the bicycle racer, we can use the equation:
vf = vi + at
Where:
vf = final velocity
vi = initial velocity
a = acceleration
t = time
Given:
vi = 11.5 m/s
a = 0.500 m/s^2
t = 7.00 s
Substituting the values into the equation:
vf = 11.5 m/s + (0.500 m/s^2)(7.00 s)
Simplifying the equation:
vf = 11.5 m/s + 3.50 m/s
Therefore, the final velocity of the bicycle racer is:
vf = 15.0 m/s
