AI Thread Summary
To calculate the work done by the pitcher on the baseball, the kinetic energy formula is used, where work equals the change in kinetic energy. Given the mass of the baseball is 0.140 kg and its speed is 30.0 m/s, the kinetic energy can be calculated as 0.5 * mass * velocity squared. This results in a kinetic energy of 63 Joules, indicating the work done by the pitcher on the ball. The discussion highlights the importance of understanding kinetic energy in solving physics problems related to motion. The problem was resolved successfully by applying the correct formula.

Homework Statement


A 0.140 kg baseball leaves a pitcher's hand at a speed of 30.0 m/s.
If air drag is negligible, how much work has the pitcher done on the ball by throwing it?



I don't even know where to start. I feel like if someone could help me find force i would be able to finish the problem

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

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

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 hanging mass'

Thread 'A cylinder connected to a hanging 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...
