5. A2 kg block is dropped from a height of 0.4 m unto a spring whose force constant k is 1960 N/m. Find the maximum compression of the spring. 6. A 10 kg body is forced against a horizontal elastic spring compressing it an amount of 0.5 m. When the body was released, it moves on a horizontal surface a distance of 3 m before coming to rest. The force constant of the spring is 500 N/m. What is the coefficient of friction between the block and the surface. 7. A 3 kg body is released from rest at a height of 10 m and slides along the path shown in the figure. Other conditions are given in the figure, compute the following: a. velocity at points B, C, D, E and G. b. the force constant of the spring if it is compressed a distance of 0.1 m. r= 3 m D E F 0000 x = 0.1 m 1 m 2 m H = 0.25 μ 0.3 C.
