There are two forces on the 2.00 kg box in the overhead view of Fig. 5-31, but only one is shown. For F 1 = 20.0 N, a = 12.0 m/s 2, and = 30.0°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) an angle relative to the positive direction of the x axis.

We analyze the motions of the two blocks separately. The top block is subjected to a contact force exerted by the bottom block. The components of this force are the normal force N 1 N 1 and the frictional force 0.400 N 1. 0.400 N 1. Other forces on the top block are the tension T i T i in the string and the weight of the top block itself A ramp, a pulley, and two boxesA ramp, a pulley, and two boxes The question (3 minutes) Box A, of mass 10.0 kg, rests on a surface inclined at 37° to the horizontal. It is connected by a lightweight cord, which passes over a massless and frictionless pulley, to a second box B, which hangs freely as shown.

May 06, 2021 · Let's say we have a system with a 10 kg weight (m 1) hanging vertically connected by a pulley to a 5 kg weight (m 2) on a 60 degree ramp (assume the ramp is frictionless).To find the tension in the rope, it's easiest to find equations for the forces accelerating the weights first. Proceed as follows: Inclined Planes Problems with SolutionsProblem 1 (No friction) A 2 Kg box is put on the surface of an inclined plane at 27 ° with the horizontal. The surface of the inclined plane is assumed to be frictionless. a) Draw a free body diagram of the box on the inclined plane and label all forces acting on the box. b) Determine the acceleration a of the box Jiskha Homework Help - Ask questions and get free help I don't understand what this question ask for.

To calculate the kinetic energy, first convert km/h to meters per second:40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2:A ball which weighs 500 grams has a Physic 231 Lecture 9 - Michigan State University Two packing crates of masses 10.0 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The 5.00-kg crate lies on a smooth incline of angle 40.0°. Find the acceleration of the 5.00-kg crate and the tension in the string.

Consider the force equilibrium along the y axis by referring to the FBD of the crate, Fig. a, +cF y = 0; N + 500 sin 45° - 10(9.8 ) - 400 sin 30° = 0 N = 827.45 N Thus, the friction is F f = m kN = 0.2(827.45) = 165.49 N. Here, F 1 and F 2 do positive work whereas F f does negative work.
