If a small marble is dropped straight downward what is the initial velocity of the marble?
The initial velocity is zero. In most basic physics problems like this one the initial velocity will be zero as a rule of thumb: the initial velocity is always zero, unless otherwise stated, or this is what you are solving for Cases where the initial velocity is not zero examples a cannon ball is shot out of a cannon at 50 mph a ball is thrown from at a speed of 15 mph etc
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
How many seconds does it take to go 30 mph?
Data is insufficient. initial velocity is 0. final velocity is 30 mph. Need acceleration to use the formula v = u + at.
What is your initial velocity if you traveled 25 miles in 2 minutes and your final velocity is 0 mile per hour?
If you traveled 25 miles in 2 minutes, your average speed was 25 miles per 2 minutes or 750 miles per hour. If your rate of deceleration was constant, your initial speed was two times 750 miles per hour or 1500 mph. I do not have enough information to determine your initial velocity because I don't know what direction you were going, and velocity is speed with direction.
How long would it take a car to accelerate from 10 mph to 45 mph if it's acceleration is 20 mph?
There is no such thing as 20 mph acceleration. 20 mph is a velocity. Acceleration is expressed as velocity per unit time e.g. mph per second or mph per minute etc.

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
What is the fastest softball ever pitched by a female?
72 mph and it was thrown by Michelle Smith hope this helps
What is the final velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
The final velocity can be calculated using the equation: final velocity = initial velocity + (acceleration x time). Plugging in the values, we get final velocity = 45 mph + (-10 mph/sec x 3 sec) = 45 mph - 30 mph = 15 mph. Therefore, the final velocity of the object is 15 mph.
How fast is an airplane traveling that accelerates at a rate of 20 mph per second for 30 seconds?
The airplane's final velocity will be its initial velocity plus its acceleration multiplied by time. Initial velocity is 0, so the final velocity will be (20 mph/s)(30 s) = 600 mph.
What is the average speed of a thrown football?
The average velocity of a thrown football is from 40 to 60 MPH. Although there has been faster velocities recorded.
What is the fastest pitch ever thrown by a woman?
I play softball so i should know ! The fastest pitch ever thrown by a woman was 80 something mph.
What is the division 1 softball overhand throw velocity average?
The average overhand throw velocity for Division 1 softball players is around 60-70 miles per hour. This velocity can vary depending on the position of the player and their level of experience and training.
How many seconds does it take to go 30 mph?
Data is insufficient. initial velocity is 0. final velocity is 30 mph. Need acceleration to use the formula v = u + at.
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 ho?
The speed of the baseball as it crosses home plate will depend on the initial velocity, the distance to home plate, any acceleration, and air resistance. This means that it's not possible to predict the exact speed without knowing more details about the specific situation. Generally, a baseball pitched at 74 mph may have a speed of around 72.2 mph when it crosses home plate due to air resistance and gravity.
What is the velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
Is a softball pitched at 68 mph the same as a baseball pitched at 98?
No...If the softball was pitched from a distance of 43 feet it is equivalent to a ball thrown just over 95 mph from a distance of 60' 6" which is the pitching distance in major league baseball. If the 68 mph pitch was thrown from 40 feet then it is equal to a 102 plus mph pitch at 60 feet 6 inches. Because speed is the relevance of time and distance then a ball thrown from 2 different distances and takes the same amount of time to travel each distance means the further of which will have to travel faster to cover more distance.
