Preparing to throw baton A in the air, you hold it at the midpoint and give it a twist with your forearm and wrist that applies a torque of 1.4 m·N for a time interval of 0.50 s. What angular speed does it have after that? P.S baton A is 80cm long and has mass of 200kg in both end points. BTW If someone can answer one more question this as well, You don't have too, but I just want to check whether if my answer is correct. What would be the moment of inertia? Without the given torque or time interval.
A horizontal force of magnitude 34.5 N pushes a block of mass 4.09 kg across a floor where the coefficient of kinetic friction is 0.609. During that displacement, the thermal energy of the block increases by 39.3 J. What is the increase in thermal ..
