A 26.84 kg dog jumps on a 86.86 kg bed. As the dog walks around on the bed, what is the average force that the bed applies to the dog?

The diagram below is a top-down view of two children pulling a 13.2-kg sled along the snow. The first child exerts a force of |F¡| = 12.0 N at an angle 0, = 45.0° counterclockwise from the positive x direction. The second child exerts a force of F2| = 6.00 N at an angle 02 = 30.0° clockwise from the positive x direction. We use a right-handed coordinate system with the +x axis and +z axis in the horizontal plane, and the +y axis out of the page. F2 (a) Find the friction force acting on the sled if it moves with constant velocity. Express your answer in vector form. f = N (b) What is the coefficient of kinetic friction between the sled and the ground? (c) What is the acceleration of the sled if F, is doubled and F2 is halved in magnitude? Express your answer in vector form. m/s? a =

The coefficient of friction between the wheels of Yamaha motorcycle and the dry pavement is 0.79. An animal walks out into the road, causing a motorcyclist to slam on the brakes. The wheels stop turning, but the tires skid along the road, causing intense friction and heat. Determine the magnitude (positive) of the acceleration which the 217-kg motorcycle experiences while skidding to a stop. The mass includes the rider. Answer: m/s/s (or m/s²)

It's a snowy day and you're pulling a friend along a level road on a sled. You've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You've been walking at a steady 1.5 m/s, and the rope pulls up on the sled at a 41° angle. You estimate that the mass of the sled, with your friend on it, is 56 kg and that you're pulling with a force of 88 N.
