A box with mass of m = 3.5kg rests on the floor of an elevator which has an upward acceleration of a. Write an expression for the sum of forces acting on the box in the y-direction (up is the positive y direction). The answer should be in terms of FN, m, g. Write an expression for the normal force Fythat the block experiences in terms of the elevator's acceleration, the blocks mass and acceleration due to gravity. If the elevator's acceleration has a magnitude g in the downward direction, what would the normal force be in newtons? What would it be if it's acceleration had a magnitude g in the upward direction?

A 3.00-kg object is moving in a plane, with its x and y coordinates given by x = 5t2 1 and y = 3t3 + 2, where x and y are in meters and t is in seconds. Find the magnitude of the net force acting on this object at t = 2.00 s.
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.
(a) What is the maximum frictional force in the knee joint of a person who supports 66.0 kg of her mass on that knee? (b) During strenuous exercise, it is possible to exert forces to the joints that are easily 10 times greater than the weight being supported. What is the maximum force of friction under such conditions? The frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. Increased frictional forces can cause further damage and pam.
