(a) Explanation The force exerted by the spring can be empirically found by the formula given in question. Write the expression for empirical formula of force. F = a x b (I) Here, a is constant, b is also constant and x is compression of the spring. Case (i): Substitute 12.9 cm for x and 1000 N for F in equation (I). 1000 N = a ( ( 12.9 cm ) ( 1 m 100 cm ) ) b Rearrange above equation for a . a = 1000 N ( 0.129 m ) b (II) Case (ii): Substitute 31.5 cm for x and 5000 N for F in equation (I). 5000 N = a ( ( 31.5 cm ) ( 1 m 100 cm ) ) b (III) Substitute 1000 N ( 0 (b) To determine The work needed to compress the spring.

Spring Potential Energy

The potential energy is the energy possessed by a body by virtue of its position or the energy held by the object due to its position relative to other objects, its force like stresses, charge, and other factors affecting the particles of the body. The p…

A spring is attached to an inclined plane as shown in the figure. A block of mass m = 2.71 kg is placed on the incline at a distance d = 0.285 m along the incline from the end of the spring. The block is given a quick shove and moves down the incline with an initial speed v = 0.750 m/s. The incline angle is = 20.0°, the spring constant is k = 505 N/m, and we can assume the surface is frictionless. By what distance (in m) is the spring compressed when the block momentarily comes to rest? m m 0 k wwww

A block of mass m = 2.50 kg situated on an incline at an angle of k=100 N/m www 50.0° is connected to a spring of negligible mass having a spring constant of 100 N/m (Fig. P8.54). The pulley and incline are frictionless. The block is released from rest with the spring initially unstretched. Ө m i (a) How far does it move down the frictionless incline before coming to rest? m (b) What is its acceleration at its lowest point? Magnitude m/s² Direction O up the incline down the incline

(a) A 15.0 kg block is released from rest at point A in the figure below. The track is frictionless except for the portion between points B and C, which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2,100 N/m, and compresses the spring 0.250 m from its equilibrium position before coming to rest momentarily. Determine the coefficient of kinetic friction between the block and the rough surface between points B and C. -A 3.00 m B C -6.00 m i (b) What If? The spring now expands, forcing the block back to the left. Does the block reach point B? Yes No If the block does reach point B, how far up the curved portion of the track does it reach, and if it does not, how far short of point B does the block come to a stop?
