Kinetic friction force acting on block is ( take g= 10m/s² ). Share with your friends. 30 kg m/sec2.Question 11. (a) State what is meant by. (i) work done, [1]. (ii) elastic potential energy. [1]. (b) A block of mass 0.40 kg slides in a straight line with a constant speed of 0.30 m s-1 along a horizontal surface, as shown in Fig. 3.1. Fig. 3.1. The block hits a spring and decelerates.Question 4 1 pts A block of mass 2.56 kg is attached to a spring of force constant 20.53 N/m. At the instant that the spring is in its equilibrium position the block is moving in the positive direction at 4.32 m/s. Find the oscillation amplitude, A. m Report your numerical answer below, assuming three significant figures. A ball of mass 0.30 kg is attached to a string and moves in a vertical circle of radius 0.60 m at a constant speed of 5.0 m s-1. What are the minimum and maximum values for tension in the string?The density of water is 1 kg/ m3 but most materials have a higher density and sink in water. Creep resistance is the resistance to a gradual permanent change of shape, and it becomes especially important at higher temperatures.A light block of mass m and a heavy block of mass M are attached to the ends of a rope. A student holds the heavier block and lets the lighter block hang below it. Then she lets go. Air resistance can be neglected. 1. What is the tension in the rope while the blocks are falling, before either hits the ground? 2. Question 4 1 pts A block of mass 2.56 kg is attached to a spring of force constant 20.53 N/m. At the instant that the spring is in its equilibrium position the block is moving in the positive direction at 4.32 m/s. Find the oscillation amplitude, A. m Report your numerical answer below, assuming three significant figures. 11. A mass weighing 8 lbf is attached to a spring (with spring constant k = 10 lbf /ft) hanging from the ceiling and comes to rest at its equilibrium. At t = 0, an external force F (t) = 2 cos 2t lbf is applied to the system. If the damping constant is b = 1 lbf · sec/ft, nd the equation of motion of the mass. corgis for adoption columbus ohio -8Ls
