What was the average force exerted by the ball on the glove?

AI Thread Summary
To calculate the average force exerted by the baseball on the glove, first determine the work done by the glove as it moves backward. The work done can be calculated using the formula for kinetic energy, which is 0.5 times the mass of the baseball times the square of its velocity. The average force can then be found by dividing the work done by the distance the glove moves. Given the baseball's mass of 140 g and speed of 30 m/s, the average force exerted on the glove is significant. Understanding these principles is essential for solving the problem accurately.

I need help with this problem. I have no idea how to start it

A baseball that weighs 140 g and is traveling at 30 m/s moves a fielder's glove 35 cm backward when the ball is caught. What was the average force exerted by the ball on the glove.

Thanks in advance

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 '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...
