- Calculate the magnitude of the normal force on a 25.2 kg block resting on a surface that is tilted up at a 40.8° angle with respect to the horizontal.A stubborn dog is being walked on a leash by its owner. At one point, the dog encounters an interesting scent at some spot on the ground and wants to explore it in detail, but the owner gets impatient and pulls on the leash with force F ⃗ = (98.0i ^ + 132.0j ^ + 32.0k ^ )N along the leash. (a) What is the magnitude of the pulling force? (b) What angle does the leash make with the vertical?A loaded penguin sled weighing 68.0 N rests on a plane inclined at angle θ = 18.0° to the horizontal (see the figure). Between the sled and the plane, the coefficient of static friction is 0.290, and the coefficient of kinetic friction is 0.150. (a) What is the minimum magnitude of the force F→, parallel to the plane, that will prevent the sled from slipping down the plane? (b) What is the minimum magnitude F that will start the sled moving up the plane? (c) What value of F is required to move the sled up the plane at constant velocity?
