Time left 1:52:02 As shown in the figure, a cannonball (mass = 17.60kg, diameter = 0.18m) is fired upward from the edge of a vertical cliff. It leaves the edge of the cliff with an initial velocity of 15 m/s directed at e from the horizontal and experiences no appreciable air resistance as it travels. The projectile reaches maximum height at point P and then falls and strikes the ground at point Q. Let g be 9.81 m/s. 0 P h X Q How high is the cliff (h=?) if 0 =45 and the range x = 42.7 m? Write your answer without decimal place and unit must be included.
