I have the question "An arrow is fired from a height h meters at a speed of 55 m/s and at an angle of 5 degrees above the horizontal. The arrow hits a target at a horizontal distance of 60 m from where it was fired and at a vertical height of 1.2 m.
a) show that the time for which the arrow is in the air before it hits the target is 1.10 seconds (to 3.s.f).
b) Find the value of h. "
Here is my attempt for part a) :
However I do not get the answer of 1.10 seconds what have I done wrong here ?
Here is my attempt for part b) is this correct ?
