If you dropped a ball off a building from 84 meters high how long would it take to hit the ground?
Assuming no air resistance, it would take about 4.5 seconds for the ball to hit the ground when dropped from 84 meters high. This time can be calculated using the formula for free fall: time = sqrt(2h/g), where h is the height (84m) and g is the acceleration due to gravity (9.81 m/s^2).
Why doesn't a ball bounce as high as dropped?
When a ball is bounced, some of the initial energy is used to deform the ball upon impact with the ground. This deformation causes some of the energy to be converted into other forms, such as heat and sound, resulting in a lower bounce height compared to the height it was dropped from.
A ball is dropped from a height of 128 meters Each time the all bounces to half of its previous height After one bounce the ball readches a height of 64 meters How high did the ball reach after the 7?
After the 7th bounce, the ball will reach a height of 1 meter. This is because after each bounce, the ball reaches half of its previous height. So, after 1 bounce it reaches 64 meters, after 2 bounces it reaches 32 meters, after 3 bounces it reaches 16 meters, and so on, until it reaches 1 meter after the 7th bounce.
What If a ball is dropped from the top of a building and it hits the ground 1.0 seconds later.how high is the building?
The height of the building can be calculated using the formula: h = (1/2)gt^2, where h is the height, g is the acceleration due to gravity (9.8 m/s^2), and t is the time taken to reach the ground (1.0 seconds in this case). Substituting the values, we get h = (1/2)(9.8)(1.0)^2 = 4.9 meters. Therefore, the height of the building is 4.9 meters.
Why didn't the ball bounce back to it's original height?
When a ball is dropped, some of its energy is lost to other forms like sound and heat upon impact with the ground. This energy loss results in a decrease in the ball's upward velocity, preventing it from returning to its original height during the bounce.
If a ball is dropped from a height of 128 meters how high did the ball reach after the 7th bounce?
3 ft
Which will hit the ground first a ball thrown horizontally at 2 meters per second off a building 20 m high or a ball dropped by a hand at the same height?
They should reach the ground together, since their initial vertical speed is the same, namely zero.
A rock is dropped from a cliff and hits the ground 6.0 seconds later How high is the cliff?
176.4 meters
A ball is thrown horizontally at 20 meters from the top of a cliff 50 meters high How far from the base of the cliff does the ball strike the ground?
64 METERSA+
A ball is thrown horizontally at 20 m s from the top of a cliff 50 meters high How far form the base of the cliff does the ball strike the ground?
64 metersIf a ball is thrown horizontally at 20 m/s from the top of a cliff that is 50 meters high, the ball will strike the ground 64 m from the base of the cliff (20m/s x 3.2 s).
Why doesn't a ball bounce as high as dropped?
When a ball is bounced, some of the initial energy is used to deform the ball upon impact with the ground. This deformation causes some of the energy to be converted into other forms, such as heat and sound, resulting in a lower bounce height compared to the height it was dropped from.

A ball is thrown horizontally from a cliff at a speed of 15 ms and strikes the ground 45 meters from the base of the cliff How high was the cliff rounded to the nearest meter?
Answer: 44 meters
How high will a ball bounce when dropped from 5ft?
i think it will be 35inches
A ball is thrown horizontally at 20 m s from the top of a cliff 50 meters high How long does it take the ball to reach the ground?
"3.2" or "3.20" please put all of that
In an investigation:You drop a tennis ball from three different heights: 1 meter, 2 meters, and 3 meters above the ground. You measure to see how high the ball bounces.What is an independent variable?
The weight and the height because the gravity is constant.
Feather a tennis ball and a bowling ball are dropped from a high tower on the moon's surface Which object hits the ground first?
Because the earth is bigger than both so they get pulled down with gravity at the same time
