A ball falls from the height of 10 m. 1st bounce: 0.5 * 10 = 5 m 2nd bounce: 5 * 0.5 = 2.5 m 3rd bounce: 2.5 * 0.5 = 1.25 m 4th bounce: 1.25 * 0.5 = 0.625 m After that the ball hits the ground the 5th time. Total distance: 10 + ( 5 * 2 ) + ( 2.5 * 2 ) + ( 1.25 * 2 ) + ( 0.625 * 2 ) = = 10 + 10 + 5 + 2.5 + 1.25 = 28.75 m Answer: The total vertical distance the ball has traveled when it hits the ground the 5th time is 28.75 m.
Step-by-step explanation: You honestly just need to divide each distance by 2 then add them together. First time it drops it goes down 10 meters. Then up five and back down. Then 2.5 meters then back down. Then 1.25, back down then .625 the back down.
At the end if you add together the total vertical distance you should get 28.75. If that is wrong well then the questions needs to be worded differently.
to prove that 6720. Sin 40. Sin 60. 80 equals 3 you'd have to divide 16 by 20 multiply subtract both sides by 3 which is 24x + 6x + 8x + -14 equals 40 40 + 20 equals 16 - -40 equals 80 which equals to 3
