A team of eight dogs pulls a sled with waxed wood runners on wet snow (mush!). The dogs have average masses of 19.5 kg, and the loaded sled with its rider has a mass of 215 kg. Calculate the magnitude of the acceleration (in m/s2) starting from rest if each dog exerts an average force of 170 N backward on the snow. What is the magnitude of the acceleration (in m/s2) once the sled starts to move?
A 66-kg man stands on a bathroom scale inside an elevator. The scale measures in units of newtons. (a) The elevator accelerates upward from rest at a rate of 1.15 m/s2 for 1.50 s. What does the scale read during this 1.50 s interval? N (b) The elevator continues upward at constant velocity for 8.50 s. What does the scale read now? (c) While still moving upward, the elevator's speed decreases at a rate of 0.650 m/s2 for 3.00 s. What is the scale reading during this time?
The diagram shows overhead views of four situations in which forces act on a block that slides on a frictionless ice surface. In which situations would it be possible for the block to move along the floor with a constant velocity? (Assume the magnitudes of the forces can be adjusted slightly). I do not understand this at all. I know gravitational force is downwards, and frictional force is opposing the pushing force, but how do I solve this?

A block of mass m1 = 40 kg on a horizontal surface is connected to a mass m2 = 16.0 kg that hangs vertically as shown in the figure below. The two blocks are connected by a string of negligible mass passing over a frictionless pulley. The coefficient of kinetic friction between m1 and the horizontal surface is 0.23. (a) What is the magnitude of the acceleration (in m/s2) of the hanging mass? (b) Determine the magnitude of the tension (in N) in the cord above the hanging mass.

A customer sits in an amusement park ride in which the compartment is to be pulled downward in the negative direction of a y axis with an acceleration magnitude of 1.58 g, with g = 9.80 m/s2. A 0.492 g coin rests on the customer's knee. (g) How long does the coin take to reach the compartment ceiling, 2.6 m above the knee? What are projections of the actual force on the coin on (h)x-axis, (i)y-axis, (j)z-axis and projections of the apparent force according to the customer's measure of the coin's acceleration on (k)x-axis, (l)y-axis, (m)z-axis?
