The spring constant for a single spring that replaces a configuration of springs is called its effective spring constant. Write an expression for the effective spring constant for a side-by-side spring configuration in terms of the two spring constants k1 and k2. Write an expression for the effective spring constant for an end-to-end spring configuration in terms of the two spring constants k1 and k2. Is the effective spring constant larger when the two springs are connected side-by-side or end-to-end? Explain your reasoning.

A block with a mass m = 2.5 kg is pushed into an ideal spring whose spring constant is k = 4520 N/m. The spring is compressed x = 0.066 m and released. After losing contact with the spring, the block slides a distance of d = 2.25 m across the floor before coming to rest. a. Write an expression for the coefficient of kinetic friction between the block and the floor using the symbols given in the problem statement and g (the acceleration due to gravity). (Do not neglect the work done by friction while the block is still in contact with the spring.)
Two identical springs are connected in series as shown, each spring has a spring constant of 98 N/m. What is the spring constant of the overall two-spring system, in N/m?

A 79.2-kg climber is scaling the vertical wall of a mountain. His safety rope is made of a material that, when stretched, behaves like a spring with a spring constant of 1.30 x 103 N/m. He accidentally slips and falls freely for 0.570 m before the rope runs out of slack. How much is the rope stretched when it breaks his fall and momentarily brings him to rest? Number i Units
