The time needed by the bike to reach the final velocity is 3 .75 seconds ,Option C is the write answer.
<h3>What is Velocity ?</h3>
It is defined as the distance covered by an object in a given amount of time. It is a vector quantity , its unit is m/s , km/hr etc.
It is given in the question that
Initial Velocity = 20m/s
Final Velocity = 35m/s
Acceleration = 4m/sq.s
Time = ?
The equation of motion
v = u +at will be used
35 = 20 + 4 * t
15 = 4* t
t = 3.75 seconds
Therefore the time needed by the bike to reach the final velocity is 3 .75 seconds.
