What is the velocity of the ball.? please help.!?

Question

it i throw a ball 210 feet

and the ball weighs 5.25 ounces (148.83 grams)

then how fast am i throwing the baseball.?

please help me out.

i really need to know.

i know it has to do with the

distance = mass over velocity formula

just moved around

Answer 1

idk but can you go on aim for a minute i got to ask u a couple questions...i already added ur screename sexyy_mexy??

mines mrevan10 if thts not urs jus add me

thanks...

Answer 2

Distance = mass/velocity

210=5.25/V

210/V=5.25

5.25/210=V

0.02m/s=V or  0.7m/s

Answer 3

I will assume that you threw the baseball vertically upwards and ignoring any air resistance, the formula that applies to this problem is

Vf^2 - Vo^2 = 2gs

where

Vf = final velocity of the ball = 0 (when ball reaches its peak)

Vo = initial velocity at which ball was thrown

g = acceleration due to gravity = 32.2 ft/sec^2

s = height attained by baseball = 210 feet

Also, note that this problem is in the category of freely falling bodies hence the mass is not relevant to the solution.

Substituting values,

0 - Vo^2 = 2(-32.2)(210)

NOTE the negative sign attached to the acceleration due to gravity. This simply means that the ball is slowing down as it is going up.

Therefore,

-Vo^2 = -13524

Vo = 116.29 ft/sec.

3000 miles an hour
