Question

An airplane needs to reach a velocity of 199.0km/h to take off. On a 2000-m runway, what is the minimum acceleration necessary for the plane to take flight? Assume the plane begins at rest at one end of the runway

Answer 1

options.
0.99 m/s2
0.92 m/s2
0.76 m/s2
0.84 m/s2

Answer 2

Answer 3

\[\large v_f^2 = v_i ^2 +2 a \Delta x\]vf and vi are final and initial velocities respectively, a is acceleration, delta x is displacement

Answer 4

Make sure to convert km/h to m/s.

Answer 5

thank you and i got 0.76 m/s2
