Question 9 10 pts A hollow cylinder of outer radius R = 14 cm and mass M = 100 g with moment of inertia about the center of mass Icom = MR2 starts from rest and moves down an incline tilted at an angle 0 = 38° from the horizontal. The center of mass of the cylinder has dropped a vertical distance h= 131 cm when it reaches the bottom of the incline. The coefficient of static friction between the...
Question 2 10 pts A block of mass m = 4.0 kg is dropped from height h = 74 cm onto a spring of spring constant k = 1530 N/m (See the figure below). Find the maximum distance the spring is compressed. (Your result must be in meters and include 2 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g = 9.8 m/s 2.) pecccccee
10 pts Question 8 Am 1= 24.0-kg object and a m 2 = 6.0-kg object are suspended, joined by a cord that passes over a pulley with a radius of R= 10.0 cm and a mass of M = 3.60 kg as seen in the Figure. The cord has a negligible mass and does not slip on the pulley. The pulley rotates on its axis without friction. The objects start from rest d = 4.20m apart. Treat the pulley as...

Question 8 10 pts A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.72 of his/her regular weight. Calculate the acceleration of the elevator and find the direction of acceleration. (Choose upward as the positive direction and express the direction of the acceleration using the sign of the result, which must be in units of mis and include 2 digit after the decimal point. Maximum of 5%...
Question 5 10 pts In the figure, take i = 0.53 A and R = 1.9 cm. Find the magnitude and direction (into or out of the page) of the net magnetic field at point P. (Choose out of the page as the positive z-direction and express the magnetic field with the sign of the result, which must be in multiples of 10 - Teslas and include 1 digit after the decimal point. That means if you get a result...
