A projectile is fired with an initial speed of 65.8 at an angle of 39.6 above the horizontal on a long flat firing range. Determine the speed and direction (angle) of the projectile 1.41 seconds after firing.
The Attempt at a Solution
Before asking these 2 questions, I was asked to find the max height, time spent in air, and the total horizontal distance covered and found correctly 89.8 m, 8.56 sec, and 434 m. At first I plugged in numbers to the equation to get the speed at 1.41 and got an answer of 52 m but that was incorrect. I'm also not sure if I can find the angle at 1.41 seconds without knowing the height.
