If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi kx, where k is a constant coefficient and x is the position of the object. Find the law describing the total force acting on this object.
Express answers in significant figures and scientific notation only. An athlete slides down from rest 40.0 meter along an icy hill which is 35 degrees from the horizontal. He then continues sliding on the level ice. a) If the coefficient of kinetic friction between the athlete and ice is 0.20 (neglect air resistance) find speed (m/s) of the athlete at the foot of the plane. b) find the distance (m) from the foot of the plane to the point where he has landed to the level ice
An athlete pulls a box E of mass m = 70kg down an incline, as shown. The coefficients of friction between the box and the incline are us-0.40 and uk-0.30.

A block is placed on a wooden plank, which is initially horizontal. One end of the plank is slowly raised to make it more and more inclined, and for a while the block stays in place on the plank and doesn't slide due to static friction. Finally, when the plank reaches an incline of 56.3oabove horizontal, the block begins to slide. What is the coefficient of static friction between the block and the plank?
You are pushing a wooden crate against a rubber floor. The two surfaces have a static coefficient of friction of 0.45 and a kinetic coefficient of friction of 0.38. The floor is horizontal, and the crate has a mass of 25.0 kg, and is initially at rest. You are pushing with a horizontal force of 155 N. What is the magnitude of the force of friction in this case? Give your answer in units of N, to three significant figures.

Two blocks are joined by an inextensible cable as shown. The mass of block A is 196.1 kg and the mass of block B is 260.9 kg. If the system is released from rest, determine the acceleration (in m/s2 ) of block B. Assume that the coefficient of friction between block A and the plane is μk = 0.45 and that the pulley is weightless and frictionless. Round off only on the final answer expressed in 3 decimal places. Use g = 9.81 m/s2

As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 61.0 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 6.00 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine (a) the salmon’s acceleration and (b) the magnitude of the force F during this interval.
