Problem 2: A water balloon is thrown from the window of two storey building with an initial horizontal velocity of 12m/s. if the window is 10m above the ground, calculate the following: a. The time for the balloon to hit the ground. b. The maximum horizontal distance travelled by the balloon: and C. The magnitude of the velocity at the instant it hits the ground. (a.) t - (b.) x= vit (C.) Vir = - gt Given: Solution: Answer. For 5 points encircle the letter of the correct answer. A ball is thrown upward at an angle of 30 degrees above the ground. Which of the following statements us TRUE regarding the velocity and acceleration of the ball when it reaches its maximum height? a. Velocity is zero while acceleration is non-zero. b. Velocity is non zero but the acceleration is zero. C. Both the velocity and acceleration are zero. d. Both the velocity and the acceleration are non-zero
