25) A child throws a ball with an initial speed of 8.00 m's at an angle of 40.0' above the horizontal. The ball leaves her hand 1.00 m above the ground and experience negligible air resistance. (a) What is the magnitude of the ball's velocity just before it hits the ground? (b) At what angle below the horizontal does the ball approach the ground? 26) A projectile is fired from point 0 at the edge of a cliff, with initial velocity components of Vox =60.0 m/'s and voy = 175 m/'s, as shown in the figure. The projectile rises and then falls into the sea at point P. The time of flight of the projectile is 40.0 s, and it experiences no appreciable air resistance in flight. What is the height of the cliff? Vo P
