Determine the maximum weight w the man can lift with constant velocity using the pulley system, without and then with the "leading block" or pulley at a. the man has a weight of 201 lb and the coefficient of static friction between his feet and the ground is μs = 0.61.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

snell's law

refractve index = sin incidence / sin refraction
