Some fish have a density slightly less than that of water, and must exert a force (by swimming) to stay barely submerged. Part (a) What force must a grouper of mass m exert to stay submerged in salt water of density ρw if its body density is ρf? Part (b) What is this force, in newtons, if the fish's mass is 82.5 kg, the density of the water is 1025 kg/m3, and the density of the fish's body is 1015...

(a) When rebuilding her car's engine, a physics major must exert 350 N of force to insert a dry steel piston into a steel cylinder at a constant velocity. What is the magnitude of the normal force between the piston and cylinder? (Assume the coefficient of kinetic friction is 0.3.) N (b) What magnitude force would she have to exert if the steel parts are oiled, so that the coefficient of friction is 0.03?

Problem 3.24 What is the magnitude of the force he must exert on the rope in case a? Figure 1) Express your answer with the appropriate units. Constants The person wants to cause the 240 lb crate to start sliding toward the right. To achieve this, the horizontal component of the force exerted on the crate times the normal force exerted on the crate by the floor. In Fig. a, the person pulls on the rope in the direction shown....
