**13. A 30.0-kg block is rest- ing on a flat horizontal table. On top of this block is resting a 15.0-kg block, to which a horizontal spring is attached, as the drawing illustrates. The spring constant of the spring is 325 N/m. The coefficient 15.0 kg 30.0 kg of kinetic friction between the lower block and the table is 0.600, and the coefficient of static friction between the two blocks is 0.900. A horizontal force F is applied to the lower block as shown. This force is increasing in such a way as to keep the blocks moving at a con- stant speed. At the point where the upper block begins to slip on the lower block, determine (a) the amount by which the spring is compressed and (b) the magnitude of the force F.

The diagram shows all the forces on an object with mass m = magnitude of the acceleration of the object? 89 kg. What is the 480 N Select one: O 9.4 m/s? 30° O 6.0 m/s? 3.0 m/s? 120 N O 4.5 m/s sine and cosine reversed. Check that you didn't get 11.5 m/s? 240 N
A massless spring with spring constant 26 N/m hangs vertically. A body of mass 1.0 kg is attached to its free end and then released. Assume that the spring was unstretched before the body was released. Find how far below the initial position the body descends. I don't understand why I'm getting this first part wrong specifically because the formula is just x= mg/k because F=kx.
The weight of the crate is equivalent to the resultant of the forces exerted by cords. The tension in cord AC is 813 N and that of cord AD is 862 N. If the stretch exerted to the spring is 693.7 N, what is the weight of the crate? 2 m 60° 135° 2 m 120° 1 m В k = 1.5 kN/m
A m1 = 1.50-kg aluminum block and a m2 = 6.10-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle θ = 32.0°) as shown in the figure. (For aluminum on steel, μs = 0.61 and μk = 0.47. For copper on steel, μs = 0.53 and μk = 0.36.)
A 10 kilogram object suspended from the end of a vertically hanging spring stretches the spring 9.8 centimeters. At time t = 0, the resulting mass-spring system is disturbed from its rest state by the force F(t) = 80 cos(8t).

Two blocks A and B have a weight of 10 lb and 6 lb , respectively. They are resting on the incline for which the coefficients of static friction are uA = 0.15 and uB= 0.25. Determine the incline angle ?theta for which both blocks begin to slide. What is the friction force under each of the blocks when this occurs? The spring has a stiffness of k = 2lb lb/ft and is originally unstreched.

Both blocks are released from rest.Using the single-system approach, what is the acceleration of the system?a= ms2 Block A is on a table and block B is hanging off the table on a rope connecting the two blocks*Round your answer to the nearest thousandth if necessary.
A movie stunt performer is filming a scene where he swings across a river on a vine. The safety crew must use a vine with enough strength so that it doesn't break while swinging. The stunt performer's mass is 90.0 kg, the vine is 11.0 m long, and the speed of the stunt performer at the bottom of the swing has been determined to be 7.40 m/s. What is the minimum tension force (in N) the vine must be able to support without breaking? Aa N Need Help? Read It

Try again. A 4.6 kg body is at rest on a frictionless horizontal air track when a constant horizontal force F acting in the positive direction of an x axis along the track is applied to the body. A stroboscopic graph of the position of the body as it slides to the right is shown in the figure. The force F is applied to the body at t = 0, and the graph records the position of the body at 0.50 s intervals. How much work is done on the body by the applied force F between t = 0 and t = 1.8 s? 0.5s -1.0 s 1.5s 2.0 s 0.2 0.4 0.6 0.8 x (m) Number To.8 Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work SHOW HINT LINK TO TEXT LINK TO SAMPLE PROBLEM VIDEO MINI-LECTURE to search 10:33 PM ENG 4/4/2021 ASUS 13) 16 17 1ghome 3 4 R U F G ト
