an airplane starts from rest and accelerates at a constant 3.00m/s2 for 30.0s before leaving the ground.

Question

a). how far did it move?
b). how fast was the airplane going when it took off?

Answer 1

a. d = 0.5a*t^2.
d = 0.5*3*30^2 = 1350 m.

b. V = a*t = 3 * 30 = 90 m/s.

Answer 2

An airport runaway is 150 n long an airplane accelerates at 2 m/ sec 2
a, what is the final speed of the plane if it covers the entire runaway?

Answer 3

An airplane starts from rest and accelerates east at a constant rate of 3 m/s2 for 30 seconds.
What is the displacement
