Question 2 (20 points) A physics student from Pittsford throws a ball thrown horizontally from the top of a building with a speed of 8 m/s. The student measures the height of the building to be 15m What is the ball's acceleration in x and y components? a- What is the ball's initial vertical () velocity? Viy How long does it take for the ball to hit the ground? How far away did the ball land from the building m's Word Bank: 20 -4.9 0 1.75 -9.8 7 4.9 14 230 1.9 Blank 1: Blank 2: Blank 3: Blank 4: Blank 5:

Explanation / Answer

ax = 0

ay = -g = -9.81 m/s^2

viy = 0

y = viy*t+1/2ay*t^2

15 = 1/2*9.8*t^2

t = sqrt(2*15/9.8) = 1.75 sec

distance x = vix*t = 8*1.75 = 14 m
