Answer:
The final velocity of the motorcycle, v = 67 ft/s
Explanation:
Given that,
Acceleration of the motorcycle, a = 3.0 ft/s²
Initial velocity of the motorcycle, u = 22 ft/s
Time interval to reach final velocity, t = 15 s
The final velocity of the motorcycle, v = ?
From the equations of motion
v = u + at
Substituting the values in the above equation
v = 22 ft/s + 3.0 ft/s² · 15 s
= 67 ft/s
Hence, the final velocity of a motorcycle is v = 67 ft/s
