Question on impulse, does it assume elastic collision?

AI Thread Summary
The discussion revolves around calculating the force required to hit a golf ball at a velocity of 76.2 m/s, given its mass of 0.0459 kg and a time of interaction of 0.0005 seconds. The calculated impulse leads to a force of 6998 N, but there is a question about whether this should be adjusted to 10766 N due to the coefficient of restitution of 0.65, which indicates the collision is not perfectly elastic. The coefficient suggests that energy is lost during the collision, contradicting the assumption of a perfectly elastic collision. Therefore, the force calculation must consider the efficiency of the collision as indicated by the coefficient of restitution. Understanding these dynamics is crucial for accurate physics modeling in sports.

Force required to hit a golf ball 76.2 m/s
Does the impulse assume the collision is perfectly elastic?

I am doing a problem on golf...

mass of golf ball .0459 kg
velocity of ball is 76.2 m/s
time of interaction is .0005 seconds
coefficient of restitution is .65 (how efficient the collision is)


impulse - F(∆t)



F=6998 N
but would the force actually be 10766N (6998/.65) since the coefficient of restitution is .65?

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 hanged 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...
