Finding average force with out taking mass into account

AI Thread Summary
To find the work done on a .045kg ball that takes off at 41m/s, the kinetic energy formula can be applied, resulting in 38.145 Joules of work. The average force can be calculated using the work-energy principle, where the work done equals the force multiplied by the distance the ball moves while in contact with the club. By ignoring the mass of the ball, the average force can be derived from the work done divided by the distance of .010m. The discussion emphasizes using the relationship between work, force, and distance to solve the problem effectively. Understanding these principles allows for the calculation of average force without needing to factor in the mass directly.

If a .045kg ball takes off at 41m/s after being hit,

a.) How much work is done on the ball?

b.) Assume that the force of the club acts parallel to the motion of the ball, and that the club is in contact with the ball for .010m. Ignore the mass of the ball and find the average force applied to the ball.

I don't know how to do this. I want to take the mass of the ball into account with the F=mv formula. What do I do?

I think the question wants you to make use of the fact that the work done by a constant force is the product of that force and the distance moved in the direction of that force.
 
Excellent! That was exactly what I needed. Thanks!
 
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...
