Question

An aircraft has a liftoff speed of 33 m/s. What minimum constant acceleration does this require if the aircraft is to be airborne after a take-off run of 240 m?

Answer 1

I found: `2.27m/s^2`

Explanation:

We can use the general relationship from kinematics:
`v_f^2=v_i^2+2as`
where:
`s=` distance;
`a=`acceleration;
`v_i=0m/s` is the initial velocity;
`v_f=33m/s` is the final velocity.
So:
`33^2=0^2+2*a*240`
`a=1089/480=2.27m/s^2`
