How do you calculate the speed of a ball during free fall from 55m high?

Using one of the formulae for constant acceleration: vf2 = vi2 + 2as, where vf is the final velocity, vi is the initial velocity (omit this term in this case, since the initial velocity is zero), a is the acceleration (9.8 in this case), and s is the distance.

What explains why the cart always catches the ball and the ball doesn't fall behind the moving cart?
Because the ball and the cart are moving at the same forward speed.
Will a feather or a wooden ball or a steel ball will fall faster in vacuum?
All will fall at the same speed in vacuum because there will be no air resistance. The gravity will pull all objects in the same force.
Does the size of the ball effect how fast it falls?
Everything falls at the same speed. the only variable is drag. For instance a feather & a bowling ball would fall at the same speed in a vacuum, but not through the air.
What two things fall at the same speed?
A marble and a bowling ball fall at the same acceleration speed. Anything with the exact same shape falls at the same velocity. 10 meters/s/s
Does the speed of a ball rolling down a ramp change with the kind of material from which the ball is made?
The speed at which an object falls is not affected by its weight or mass, so a solid stone ball should fall just as quickly as a hollow wooden ball. But a ball made of a rougher material could slow it down. The material of the ball should only matter if affects how smooth the ball is.
Why can you only calculate a stone's average speed during its fall?
That is just not true! If you can calculate its average speed you should be able to calculate its speed at any point in time during its flight, including its final velocity.
Do a pin and a ball fall at the same speed?
iT DEPENDS IF THE BALL IS LIGHT THE LIGTER MOSTLIKLEY TO HAVE THE SAME SPEED.

What is the speed of a fall of 80 feet in 2.5 seconds?
average speed = (distance) / (time to cover the distance) = (80/2.5) = 32 ft/sec.We know that the speed was not constant during the 2.5 seconds. But with the information given,32 ft/sec average is the only thing we can calculate.
If you are in a moving car and if you throw a ball vertically up why does the ball fall in your hand?
Because both You and the ball (and everything else in the cabin for that sake) are moving with the same speed as the car :)

What speed does a bowling ball at free fall?
It depends on the time of fall or the distance of fall: Vb = g*t or Vb = √(2*g*y) where y is the distance fallen
What two things fall at the same speed?
A marble and a bowling ball fall at the same acceleration speed. Anything with the exact same shape falls at the same velocity. 10 meters/s/s
When will Dragon Ball Z season seven come out?
Untold, yet easy to calculate, late fall, 2008. USER: Cooljoe

Why are bowling balls heavy?
So the ball can pick up more speed. For example, if you drop a feather on the ground, it takes a longer time to fall than a heavier object, such as a notepad. A bowling ball is heavier to gain speed faster.
