Calculating Average Force for a Baseball Batting Exercise

AI Thread Summary
To calculate the average force acting on a baseball during a batting exercise, the correct formula is Fnet = mv/t, where m is the mass in kilograms, v is the final velocity, and t is the time of contact. The mass of the baseball is given as 145 g, which should be converted to 0.145 kg for accurate calculations. Using the values provided, the average force can be calculated as Fnet = 0.145 kg * 84 m/s / 0.09 s. The initial calculation of 135,333.3 was incorrect due to the mass not being in the proper unit. The final answer should be expressed in Newtons for clarity.

Physics average force need help!

Homework Statement



A coach is hitting pop flies to the outfielders. If the baseball (mass = 145 g) stays in contact with the bat for 0.09 s and leaves the bat with a speed of 84 m/s, what is the average force acting on the ball?

Homework Equations



Fnet=mv/ t

The Attempt at a Solution


Fnet= 145 x 84 / .09
I got 135333.3 and this wa incorrect. I think I am using the wrong equation... Please help!

Problem looks like units, assuming you were supposed to give your answer in Newtons. If you want the force in Newtons, you need the mass to be given in kg.
 
Thank you very much!
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
