An aircraft has a liftoff speed of 33 m/s. what is the minimum constant acceleration an
airplane must have to reach that takeoff speed if the runway is only 240 m long?

The minimum acceleration for the air plane is 2.269m/s2.

Explanation: To solve such problem the equation of motion are applicable.

The initial velocity is 0 since the airplane was initially standing. We are going to use this equation

V^2=U^2+2as

33^2=0+2a (240)

a= 2.269m/s2

radial fractures in a piece of glass look most like which of the following?

a. spokes of a wheel

b. a circle

c. a zig zag

d. none of the above

the correct answer is a. spokes of a wheel

hope this (:

the answer is the index of refraction of the second medium is higher. i just took the test.
