A baseball is seen to pass upward by a window 25M above the street with a vertical speed of 12ms if the ball was thrown from the street what was its initial speed?

for this problem use the formula V(final)= V0 +A*t
V0=36ms
V(final)= 12ms
A= -9.8m/s^2
t=?
plug into the equation
12= 36 + (-9.8)t
-24= (-9.8)t
t=2.4 seconds

How many inches of 60 yards?
This depends entirely on the trajectory of the initial launch and the aerodynamics of the object thrown. The vertical forces of gravity operate independently of the horizontal forces of acceleration and deceleration (i.e. the throw and the friction that will slow the object as is travels through the air). As soon as the object is thrown is begins to fall (because of gravity). If it is to make it 60 yards before gravity pulls it to the ground, the time it takes to fall must equal the time it take to travel 60 yards. You can make the object travel 60 yards by either increasing the speed it travels or increasing the distance it has to fall. It is most effective to do both. Throw hard and throw high. So... as asked, this question has no actual answer without more information about the object being thrown and the trajectory with which it is thrown.
Describe contact force and noncontact force that affect the motion of a baseball a pitcher has thrown the ball?
The contact force will keep the ball moving but as the ball goes farther the ball slows down that's were the non contact force comes in it makes the ball not in contact
Does a baseball of softball have more kinetic energy when thrown at 35mph?
KE = 1/2mv2, where m is mass in kg, and vis velocity in m/s. Since both the baseball and the softball are thrown at the same velocity, the difference in KE comes down to mass. A baseball has a mass of 0.142kg - 0.149kg, and a softball has a mass of 0.177kg - 0.198kg. Therefore, since the softball has the greater mass, the softball would have more kinetic energy. The 2 after the v is supposed to be a superscript and is supposed to mean velocity squared.
What happens when batteries are thrown away?
Nothing at all.
HOW MUCH TRASH IS THROWN AWAY IN America per year?
On the site students.arch.utah.edu, it states that 1 million pounds of trash is thrown away per person every year.
A ball is thrown horizontally from a window on the second floor of a building What is the vertical component of its initial velocity?
If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
Is acceleration greater when the object is thrown vertically or horizontally?
Acceleration is dependent on the initial velocity of how fast the object is leaving the projectile. The vertical acceleration is greater when the object is falling than when the object reaches the peak in height. However, if the object is thrown horizontally and there is no parabola in its shape then there is not as great of an acceleration.
What is the force that gives a thrown ball a vertical movement?
Gravity
What is the force that gives a thrown ball its vertical movement?
Gravity
If after an object is thrown no other fone and ads on it except gravity What are the vertical and horizontal components of its acceleration vector?
If the object is thrown upwards, the vertical acceleration is negative and the horizontal acceleration is zero.
A baseball was thrown from 1 m hill Assume that the ball had an initial velocity of 70 kmh 19.44 ms at 40 degreesWhat was the initial velocity on x direction?

What is the best way to analyze an object thrown into the air?
whenever an object is thrown in the air we must know the initial velocity with which the object has been thrown.
Initial velocity of a softball thrown at 30 mph?
30 mph!
Motion of a body thrown from certain height?
The body will move: * Because of its initial motion (the question states that it is thrown) * Because of gravity
