Question

An airplane accelerates from a velocity of 22 m/s to 40 m/s with an acceleration of 2 m/s2. How long does it

Answer 1

The time it takes the plane to change its velocity is 9s.

What is time?

Time can be defined the measured or measurable period during which an action, process, or condition exists or continues.

To calculate the time it takes the airplane to change its velocity, we use the formula below.

Formula:

• t = (v-u)/a.......... Equation 1

Where:

• a = Acceleration
• v = Final velocity
• u = Initial velocity
• t = time

From the question,

• v = 40 m/s
• u = 22 m/s
• a = 2 m/s²

Substitute these values into equation  1

• t = (40-22)/2
• t = 18/2
• t = 9s

Hence, the time it takes the plane to change its velocity is 9s.
