AI Thread Summary
To solve for the average force exerted by the bat on the ball, first calculate the change in momentum using the initial and final velocities of the ball. The ball's initial velocity is 13 m/s, and after being struck, it moves at 19 m/s in the opposite direction. The impulse-momentum theorem indicates that the average force can be determined by dividing the change in momentum by the time of contact, which is 0.01 seconds. The formula F = Δp/Δt can be applied, where Δp represents the change in momentum. By following these steps, the average force exerted by the bat can be accurately calculated.

Homework Statement


A 0.25 kg ball moving at 13 m/s is struck by a bat and leaves the bat traveling at 19 m/s in the opposite direction to its initial direction. If contact between bat and ball lasts for 0.01 s what is the average force exerted by the bat on the ball?

Homework Equations



F= MA

The Attempt at a Solution


0.25X (13+19) but then what solution do i use for the time

Look up the impulse-momentum theorem.
 
what does acceleration equal .. ??

Change in what / change in what ... ??

Find the initial and final velocities and change in time and u r done. ^^
 
Average force exerted by the bat on the ball = Rate of change in momentum, juz divide what u find with time.
 

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'

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...
