A shell is fired from the ground with an initial speed of 1.61 multiplied by 103 m/s at an initial angle of 39 to the horizontal.
(a) Neglecting air resistance, find the shell's horizontal range.

(b) Find the amount of time the shell is in motion.

For the first one I tried to find the horizantle component by using 1.6X10^3 Cos 39 and i got some huge number..
