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 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
