[1 point, 10 tries] When a certain spring is stretched beyond its proportional limit, the restoring force satisfies the equation F=-kx+ β x 3 . If k=11.0 N/m and β =99 N/m 3 , calculate the work done by this force when the spring is stretched 0.106 m. Answer:-5.87e-02 J 2 . [1 point, 10 tries] A 246 g block is pressed against a spring of force constant 1.67 kN/m until the block compresses the spring 13.6 cm. The spring rests at the bottom of a ramp inclined at 59.7° to the horizontal. Using energy considerations, determine how far up the incline the block moves before it stops if there is no friction between the block and the ramp. Answer: 7.41E+00 m 3 . [1 point, 10 tries] How far up the incline does the block move before it stops if the coefficient of kinetic friction is 0.310. Answer: 6.28E+00 m 4 . [1 point, 10 tries] A 0.335 kg particle slides around a horizontal track. The track has a smooth, vertical outer wall forming a circle with a radius of 1.68 m. The particle is given an initial speed of 8.40 m/s. After one revolution, its speed has dropped to 5.70 m/s because of friction with the rough floor of the track. Calculate the energy loss due to friction in one revolution....
