Momentum, Impulse, and Collisions

AI Thread Summary
To solve the problem of a baseball struck by a bat, the concepts of momentum and force are crucial. The initial momentum of the baseball can be calculated using its mass and initial velocity, while the final momentum is determined by its mass and final velocity at an angle. The average force exerted on the ball can be found using the formula for net force, which relates the change in momentum to the time of contact. It is important to treat the horizontal and vertical components of the force separately to accurately analyze the situation. Understanding these principles allows for a comprehensive approach to the collision problem.

How would I go about this problem? Any advice would be really helpful, please.
A bat strikes a 0.154 kg baseball. Just before the impact, the ball is traveling horizontally to the right at 50m/s, and it leaves the bat traveling to the left at an angle of 30 degrees about the horizontal with a speed of 65m/s. If the ball and bat are in contact for 1.75ms, find the horizontal and vertical components of the average force on the ball.

How would you include the concept of momentum in this problem, and is F=ma needed?

I could be wrong but I think you use net force = change in momentum/ change in time. F = p/t or F=mv1-mv2/t, and once you have the force you can find the x and y component.
 
you SHOULD treat the x and y components separately from the start.

Sum of F = ma is a special case of p_i + (Sum of F)dt = p_f .
 

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...
