AI Thread Summary
To determine the retarding force on a golf ball plugged in soft ground, the initial kinetic energy of the ball must be calculated using its height of 20 meters and mass of 45 grams. The gravitational potential energy converts to kinetic energy just before impact, which is then dissipated as the ball plugs into the ground. The depth of 5 cm indicates how far the ball penetrates, allowing for the calculation of the retarding force using the work-energy principle. By applying the formula for work done against the retarding force, the force can be derived. The final result provides insight into the dynamics of the ball's interaction with the soft ground.

A Golf ball is struck with a high lofted club it falls to Earth under the influence of gravity from a height of 20m. It then plugs into soft ground and comes to rest suddenly without rebound. It then plugs in a depth of 5cm. Find the retarding force which acts on the ball. It has a mass of 45 grams.

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...
