What is the speed of a 0.15 kg baseball?

What is the speed of a 0.15 kg baseball?

Final answer: The speed of a 0.15-kg baseball with 77 J of kinetic energy is approximately 40.82 m/s. This is found using the kinetic energy formula and solving for velocity.

Can accelerate a 0.15 kg ball from rest in baseball?

In a baseball, a pitcher can accelerate a 0.15 kg ball from rest to 98 mi/h in a distance of 1.7 m.

How do you calculate baseball speed?

How do you find the acceleration of a baseball?

1. a=v2−v1t .
2. v1 is the initial velocity,
3. v2 is the final velocity and.
4. t is the time taken (or the time interval in which velocity changes from initial velocity to the final velocity)
5. t=0.238s.
6. a=41−00.238ms−2.

What is the acceleration of a baseball?

We can determine the average acceleration experienced by the ball from Newton’s second law: F=m a. Using the numbers above, we obtain an average acceleration of 127,145m/s2, or 12,740 times the acceleration due to gravity!

Does weight affect velocity baseball?

As I mentioned earlier, higher bodyweight tends to mean higher GRF at the front leg, which tends to mean higher baseball velocity.

What is baseball speed?

Power pitchers, such as former American major leaguers Nolan Ryan and Roger Clemens, rely on speed to prevent the ball from being hit and throw fastballs at speeds of 95–105 miles per hour (153–169 km/h) (officially) and up to 108.1 miles per hour (174.0 km/h) (unofficially).

What is the formula for calculating speed?

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

What formula is best for calculating speed?

That is speed = distance ÷ time. Or to put it another way distance divided by speed will give you the time. Provided you know two of the inputs you can work out the third. For example if a car travels for 2 hours and covers 120 miles we can work out speed as 120 ÷ 2 = 60 miles per hour.

What is the speed of a .145 kg baseball if its kinetic energy is 109 J?

Final answer: The baseball with a mass of 0.145kg and kinetic energy of 109J has a velocity of around 39.1 m/s.

What is the instant before a batter hits a .14 kg baseball?

The instant before a batter hits a 0.14-kilogram baseball, the velocity of the ball is 45 meters per second west. The instant after the batter hits the ball, the ball’s velocity is 35 meters per second east. The bat and ball are in contact for 1.0 ×10–2 second.

What is the kinetic energy of a 0.135 kg baseball thrown at 40?

Ek=(0.135)(40.0)22 . Ek=108J .
