- Dynamics of Rigid Bodies Please help ASAP. Rate will be given accordingly. Please write your answer on paper. Thank you so much. Note: The tolerance is ±1 in the third significant digit.Two blocks are connected by a massless rope over a massless, frictionless pulley, as shown in the figure. The mass of block 2 is m2 12.1 kg, and the coefficient of kinetic friction 0.200. The angle 0 of between block 2 and the incline is µk the incline is 33.5°. If block 2 is moving up the incline at 2 constant speed, what is the mass mj of block 1? 1 kg M¡ =A roofer pulls a 25.0 kg bundle of shingles up the side of a roof that has a 29.0 ̊pitch.

- Please ignore my last question. I am sorry. I messed up the problem when I asked before. The correct one is below: An inclined plane makes an angle of 30 degee with the horizontal. (Static friction coefficent of the inclined surface is 0.4 and the kinetic friction coefficent is 0.1) A block which weighs 1 kg must pass through a gate at the bottom of the incline with a velocity of 3.0 m/s. At what distance along the incline must you realease the block?I'm having some issues understanding my physics homework. It doesnt look like what we were doing in class and I dont think I'm using the right formulas. I need some help with a & b, attached.I hang a 83-kg weight on a force spring, which registers 183.07 Newtons. With what acceleration does it pull down the spring in m/s2? Round to 2 decimal places.
