21. A physics teacher makes a pumpkin-cannon for Halloween, and uses it to launch pumpkins from the roof of the school. The roof is 10.0 m above the ground, and a pumpkin is launched with a velocity of 12 m/s at an angle of 25.0 above the horizontal. 12 m/s Ascension 25.0 T 10.0 m (A) What is the magnitude of the vertical and horizontal components of the pumpkin's initial velocity? (4%) (B) What is the maximum height reached by the pumpkin? (4%) (C) How much time is required for the pumpkin to reach its maximum height? (4%) (D) How much time does the pumpkin take until it hits the ground? (4%) (E) What is the speed (no direction required) of the pumpkin just as it strikes the ground? (4%) 21.
