A specialized research drone is climbing vertically at a velocity of 4.2 m/s.
The drone accelerates upwards at 3.2 m/s2 until its velocity is 15.4 m/s.
Calculate the time taken for this acceleration.
Use the equation:
time taken=change in velocityacceleration \text{time taken} = \frac{\text{change in velocity}}{\text{acceleration}} time taken=accelerationchange in velocity
