1. A projectile is red from a cannon With a velocity \"1,30. The cannon is a dis tance s from the bottom of a cliff of height h, and it makes an angle oz With the horizontal. The cannon is red at t = U. (a) Putting the origin of the coordinate system at the cannonj nd :1: and y as functions of t. (1)) Find y as a function of :17. (c) We want the projectile to hit the cliff just at its edge, that is at the point (3, b). What value of 1:0 Will achieve this
