Shown in the figure below is a system of two blocks. One of these blocks is resting on a surface tilted left and the other one is on a surface tilted right. The strings and the pulley have no mass. There is no friction anywhere in the problem.The characteristics of the system are given here: m1 = 4.14 kg m2 = 6.69 kg ?1 = 23.0 ?2 = 57.7 Answer all the following:What is the normal force, N1, on mass m1?  What is the normal force, N2, on mass m2?  What is the acceleration, a of the system?  What is the tension, T?

A conical pendulum is set up with a bob whose mass is 6.0 kg. When it is set in motion, at a speed of 0.60 m/s, the string makes a 12.0 degree angle with the vertical. a) Find the radius of the horizontal circle the conical pendulum traces out. b) Find the length of the string.c) Find the magnitude of the tension in the string.

Two blocks with masses M1 and M2 are connected by a massless string that passes over a massless pulley as shown. M has a mass of 2.25 kg and is on an incline of 01 43.5° with coefficient of kinetic friction 0.205. M2 has a mass of 6.35 kg and is on an incline of 02 = 35.5° with coefficient M2 of kinetic friction µz = 0.105. The two-block system is in M, motion with the block of mass M2 sliding down the ramp. Find the magnitude az of the acceleration of M2 down the incline. Figure is not to scale. a2 = m/s? * TOOLS x10

There is a block loaded with two 0.5 kg masses and is pulled at constant velocity across the table but with an applied force that is parallel to the surface of the table. theta = 0 because the force is of the same diraction as the displacement.  What are the magnitudes of the following forces:  Fg FN Ff
