Question

A shell is fired from the ground with an initial speed of 1.70 x 10^3 m/s (approximitely five times the speed of sound) at an initial angle of 55.0 degrees to the horizontal. Neglecting air resistance, find.. 
A.) the shell's horizontal range 
B.) the amount of time the shell is in motion

jack1 · Answer

so what is the horizontal component of the shells' speed? @verooo97 ?

jack1 · Answer

so use triangle theory (ie pythag theorum) to find v horizontal and v vertical

then use v (vertical) to determine time in the air

use time in the air and v horizontal to determine distance travelled (range)

jack1 · Answer

does that all make sense @verooo97 ?
