A m = 10 kg block is released from a height of h = 3 m. It travels down a frictionless circular shaped ramp to the bottom where it encounters a rough surface. It travels over this rough surface for 6 m followed by 3 m more on a frictionless surface. At this point the block compresses a spring by 0.3 m before stopping. The spring constant of the spring is 2250 N/m. Find the coefficient of kinetic friction for the rough surface.
A large piece of cork weighs 0.295 N in air, he spring scale reads 0.903 N. Find the density of the cork

Two boats start together and race across a 46 km wide lake and back. Boat A goes across at 44 km/h and returns at 48 km/h. Boat B goes across at 27 km/h, and its crew, realizing how far behind it is getting, returns at 69 km/h. Turnaround times are n..
A copper wire is 10.00 m long and has a cross-sectional area of 1.00 x10-4 m2. This wire forms a one turn loop in the shape of a square and is then connected to the battery that applies a potential difference of 0.200 V.
