Question

A plane has take off of 300km/hr.What is the acceleration if it is started from rest of 0.25 hour to take off

Answer 1

Answer:

Data: Initial velocity = 0km/h

         Final velocity = 300km/h

         Time = 0.25 h

Formula:   a = final velocity - initial velocity / time

                  a = 300 - 0 /0.25

                  a = 300/0.25

                  a = 1200 m/s/s

Answer 2

Answer:

we know acceleration(a)=change in velocity/time

here initial velocity=0

and final velocity=300km/hr

so change in velocity=300-0=300km/hr

thus acceleration (a)=300/0.25

=1200 km/ square hour
