Where x is the distance from the leading edge along the chord c and c is equal to 1.5 m. the angle of attack is 100 . calculate the the lift, drag, moments about the leading?

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.
