Q. After driving a portion of the route, the taptap is fully loaded with a total of 25 people with an average mass of 60 kg per person. In addition, there are three 15 kg goats, five 3 kg chickens, and a total of 25 kg of bananas on their way to the market. Assume that the springs have somehow not yet compressed to their maximum amount. How much are the springs compressed?
Q. At a construction site, a 22.0 {rm kg} bucket of concrete is connected over a very light frictionless pulley to a 375 {rm N} box on the roof of a building. There is no appreciable friction on the box, since it is on roller bearings. The box starts from rest. Find the acceleration of the bucket.
An archer puts a 0.26 kg arrow to the bowstring. An average force of 213 N is exerted to draw the string back 1.3 m. unless otherwise directed, suppose that air resistance is negligible. Illustrate energy bar graphs to solve the problem.
A loudspeaker of mass 24.0 {rm kg} is suspended a distance of h = 1.40 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.70 {rm m}.
The coefficient of static friction between the stone and each side of the tread channel is 0.7. While the tire surface is rotating at a maximum speed of 1 m/s, the stone flies out of the tread. The magnitude FN of the normal force that each side of t..
