Question 1181322: Do the following exercises. It is very important to draw a diagram for each problem and label the horizontal and vertical components of the variables.
1. A ball is thrown horizontally out of the balcony with an initial horizontal speed of 1.8m/s. If the balcony is 12m from the ground,
a. How much time will it take the ball to reach the ground?
b. What is the horizontal distance travelled by the ball before it hits the ground?
This is not related to algebra but I hope someone can help me. Thank you😊 Found 2 solutions by Boreal, ikleyn:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! How long does it take to reach the ground?
s=1/2(gt^2)
so t=sqrt(s/2g)=sqrt(12/19.6)=0.782 seconds to hit the ground
-
The horizontal distance is the distance it travels in that time period or 0.742*1.8, or 1.41 m, if I round at the end.
Unfortunately, the solution by @Boreal is incorrect.
I came to bring you the correct solution, changing his formulas and calculations.
How long does it take to reach the ground?
s =
so t = = = 1.564 seconds to hit the ground.
The horizontal distance is the distance it travels in that time period or 1.564*1.8, or 2.815 meters (rounded).
