I need some tips studying about 1. Angular momentum and numerical problems based on angular momentum 2. Capillary action numerical problems based on them 3.Free body diagrams for force and numerical problems based on them 4. Elastic and inelastic collisions and numerical problems based on them

So the problem is solved, right...? thanks

m = 5 kg, g = 10 m/s2, m*g*h = 250 joules, h = 250/5*10 m, h = 5 m... ?

Is it related to Energy conservation during free-fall

um... is it a question or are you helping me with the solution..?

U = m*g*h...?

what formula to use?

1. A grinding wheel of mass 5 kg and diameter 0.20 m is rotating with an angular speed of 100 rad/s. Calculate its kinetic energy. Through what distance would it have to be dropped in free fall to acquire this kinetic energy? m = 5 kg, r = 0.20/2 m = 0.10 m, g = 10 m/s2, ω = 100 rad/s 2. v =...

thanks

Yes it was the same doubt i had. can the coefficient of kinetic friction be found

S So can the force of kinetic friction be found? if so how to find

please tell me what is wrong about it?

A 1.2 kg block is resting on horizontal surface. The coefficient of static friction between block and surface is 0.5. What is the magnitude and direction of force of friction on block when magnitude of external force acting of block in the horizontal direction is 9.8 N fs = μs*N, N = mg m =...
