An arrow is shot at an angle 37° with the horizontal. It has a velocity of 47 m/s. The
acceleration of gravity is 9.8 m/s2.
What horizontal distance will it travel?
Answer in units of m.

d = 220 m  (2 s.d.)

Explanation:

If the arrow flies over a horizontal plain and air resistance is ignored.

The time of flight is twice the time that gravity takes to reduce initial vertical velocity to zero

t = 2(47sin37)/9.8 = 5.7725... s

Range is the time of flight times the initial horizontal velocity.

d = (47cos37)5.77 = 216.676...
