Question

3. A projectile leaves the barrel of a cannon with a speed of 162 feet/sec at an angle of 22.61 degrees above the horizontal. Ignoring the effects of air friction find: (a) the maximum altitude achieved by the projectile (b) the horizontal range achieved by the projectile (c) the displacement and the velocity (both are vectors in 2D) of the projectile 7.72 seconds after firing. Calculate quantities in units of feet and feet
