A 5 lb ball dropped from 2000 feet will reach a speed of approximately 117 mph when it hits the ground, neglecting air resistance. This is calculated using the kinematic equation vf = √(vi^2 + 2aΔy), where vi is the initial velocity (0 ft/s), a is acceleration due to gravity (32 ft/s^2), and Δy is the height (2000 ft).

Which has a larger wavelength a slow moving photon or a fast moving golf ball?
A slow moving photon has a longer wavelength compared to a fast moving golf ball. Wavelength is inversely proportional to speed, so the slower the object, the longer the wavelength.
How can an elephant have the same momentum as a golfball?
this question has the theoritical answer but it is not yet practically done. according to the theortical answer """"""""yes! elephant have the same momentum as a golf ball<<<<<<<<< Actually, elephants can have the same momentum as a golf ball. the equation for momentum is m x v2. m is mass, v is speed, and the two represents "speed squared". If the golf ball has a huge speed, then yes, it can have the same momentum as the elephant.
How fast was the Galileo spacecraft going when it reached Jupiter?
From what I have read it was going 50,000 mph.
Why does a golf ball make a bigger dent in the sand when dropped above the sand at higher heights?
It has more momentum from a higher height. Because momentum is always conserved, and momentum is the product of mass times velocity, more sand particles must move away faster in order to conserve the momentum of a heavy ball moving fast. The ball is moving faster from a higher height because the acceleration due to gravity (-9.81 m/s^2) increases the velocity of a falling object after each second its been falling.
Does the surface of a hill effect how fast a ball will roll down it?
Yes, the surface of a hill can affect how fast a ball will roll down it. A smoother surface will have less friction, allowing the ball to roll faster, while a rougher surface will create more friction and slow the ball down. Additionally, the incline of the hill will also impact the speed of the ball as steeper hills will cause the ball to accelerate more quickly.
How fast is a ball dropped 3 m going?
The answer will depend on whether you want the average speed during the 3 metre drop or the instantaneous speed when it has fallen 3 m.
How fast should a fast ball go?
Speed doesn't matter for fast balls, what matters is if it's going straight or not.
Is a lacrosse ball hard?
Very very hard, especially when going fast
Could an elephant have the same momentum as a golf ball why or why not?
Well, that depends on how fast the golf-ball is going, if it's going 30 mph, yes is can, If faster no.
Is it a technical foul if a player gets intentionally fouled on a fast break?
That depends. If he was intentionally fouled but the player was going for the ball, than no. If the player was not going for the ball, than yes.
How fast is a ball going when it hits the ground after being dropped from a height of 16m The acceleration of gravity is 9.8ms2?
The speed of the ball can be found using the kinematic equation: final velocity (Vf) = sqrt(2 * acceleration * distance). Plugging in the values, Vf = sqrt(2 * 9.8 * 16) = sqrt(313.6) ≈ 17.7 m/s.
If a ball travels 40 yards in 4.3 seconds how fast is it going?
It is going about 9.3 yards per second; 40/4.3.
How can you evaluate the throwing power?
im not going to tell you the fancy way but pretty much its the speed of the ball and how fast it went and how much the ball weighs
How to calculate the amount of time for a ball to reach 3 meters?
You need to know how fast the ball is going, and divide the speed by the distance, which is 3 meters.
What is the fast ball sport?
The fast ball sport is baseball, a fast ball is basically when a pitcher just throws the ball staight at the strike zone.
What is the adjective in the sentence she can hit a fast ball?
fast ball
Why is it easier to stop a soccer ball than a bowling ball?
It depends on how fast they're going. A bowling ball is much heavier, therefore has more momentum if they're both travelling at the same speed.
