Question

an aircraft climbs from an altitude of 9000 m to 12000m at an angle of 18 degrees the velocity at the begining of the climb is 900 kmh the aircraft decelerates during the manoeuvre at the rate of 1,6meter square second...calculate the velocity of the air craft at the new altitude

Answer 1

find the distance s, and then you can use the formula\[v ^{2}=u ^{2}+2as\]
where v is final velocity, u is initial velocity, a is acceleration and s is the length of the hypotenuse in the drawing.
