How much is the acceleration of a baseball thrown if the ball goes from 0 to 90 mph in a one-half-second time period?

1 mile = 5280 ft
1 hour = 3600 seconds
→ 1 mph = 1 mile/1 hour
= 5280 ft/3600 seconds
= 22/15 ft/s
v = u + at
→ a = (v - u) ÷ t
= (90 mph - 0 mph) ÷ 0.5 s
= (90 x 22/15 ft/s) ÷ 0.5 s
= 264 ft/s2
==============================
Answer #2:
180 miles/hour-second
(Exactly the same number as Answer #1.)

How do you find the acceleration of a ball that is being thrown as a projectile as it is leaving your hand... Just the acceleration as it leaves the hand?
After, and at the exact moment, the ball leaves the hand it is only accelerated by gravity if you disregard air resistance.
What is the acceleration of an object effected by gravity thrown at a 45 degree angle above the horiziontal at its highest point?
The only force acting on a projectile once launched is gravity. So the acceleration of any object launched at any angle is the acceleration due to gravity, -9.8m/s2.
Does two stones have the same acceleration if one is thrown upward from a roof and the identical one is dropped from there?
no because the higher it gets the speed increases and its do not does.
Is it possible for an object to be accelerating even though it has stopped moving?
No. A nonzero acceleration means that the velocity is changing, so it can only have a 0 velocity at a single point in time, such as when a ball thrown in the air reaches its peak.
The speed of a baseball crossing home plate after being pitched depends on its initial velocity. If thrown at 74 mph the speed over home plate will be 72.2 mph. If thrown at 50 mph the speed over home?
Speed(74) = 72.2Speed(50) = 44.7
Is the acceleration the same on an object that is drop or when its thrown?
No, the acceleration is not the same for an object that is dropped and an object that is thrown. When an object is dropped, it experiences a constant acceleration due to gravity. When an object is thrown, its acceleration can vary depending on factors such as the initial velocity and direction.
How is newtons 2nd law relevant to baseball?
the less mass the ball has (times) the acceleration the ball is moving = the force the ball was thrown at.(F=MA)
What happens to a ball thrown straight down from a bridge would have acceleration of?
The ball thrown straight down from a bridge will experience an acceleration due to gravity. On Earth, this acceleration is approximately 9.81 m/s^2 and acts in the downward direction. The acceleration will cause the ball to increase in speed as it falls towards the ground.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
Does a softball have a positive or negative acceleration when it is thrown?
When a softball is thrown, it has a positive acceleration because its velocity is increasing with time as it moves through the air.
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.
How much is the acceleration of a baseball thrown if the ball goes from 0 to 90 mph in a one-second time period?
Acceleration is change of speed / time, so in this case you have 90 miles per hour per second. While this is a valid unit of acceleration (a unit of distance divided by two time units), you may want to convert this to other units. Reminder: 1 hour = 3600 second; and 1 mile = 5280 feet.
What is the acceleration of a ball after it has been thrown into the air?
The acceleration of a ball after it has been thrown into the air is due to gravity acting on it. While the ball is in free fall, it experiences a constant acceleration of 9.81 m/s^2 downward (assuming no air resistance).
When thrown by the same person which can be thrown farther a baseball or a softball?
A baseball can
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?
The vertical component of the acceleration vector is the acceleration due to gravity (9.81 m/s^2 downward). The horizontal component of the acceleration vector is zero since there is no acceleration acting in the horizontal direction (assuming no external forces).
What happened to the ball when you thrown upward?
When a ball is thrown upward, it experiences a brief period of acceleration while moving against the force of gravity. Once the ball reaches its peak height, it begins to fall back down due to gravity.
What is the downward acceleration of a thrown object in projectile motion?
The downward acceleration of a thrown object in projectile motion is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. This acceleration acts vertically downward and affects the vertical motion of the object while the horizontal motion remains unaffected.
