QUESTION 2 A canon fires a projectile at an angle of 23 degrees with the horizontal with an initial velocity magnitude of 22.2 m/s. The projectile ultimately hits the ground in the East of the launch point. Find the magnitude of the accelaration vector 2.35 seconds after the projectile was fired. Assume the effect of air resistance is negligible. Enter the accelaration in unit of m/s.
