A block of mass (m=2.00kg) is attached to a spring of force constant k=4.05x10^2 N/m that lies on a horizontal frictionless surface. The block is pulled to a position x=5.85 cm to the right of equilibrium and released from rest. A) Find the work required to stretch the spring. B) Find the speed the block has as it passes through equillibrium.

You have a light spring which obeys Hooke's law. This spring stretches 3.04 cm vertically when a 2.90 kg object is suspended from it. Determine the following. (a) the force constant of the spring (in N/m) N/m (b) the distance (in cm) the spring stretches if you replace the 2.90 kg object with a 1.45 kg object cm (c) the amount of work (in J) an external agent must do to stretch the spring 8.10 cm from its unstretched position J

A 1.5 kg block is forced against a horizontal spring, compressing the spring 0.17 m. When released, the block moves on a horizontal table top for 1.01 m before coming to rest. The spring constant is 112 N/m. Determine the coefficient of kinetic friction between the block and the table

A spring of negligible mass has force constant k = 1600 N/m. How far must the spring be compressed for 3.20 j of potential energy to be stored in it? 7) %3D a) b) The spring is placed vertically with one end on the floor. A 1.0-kg book is the droped from a height of 0.80 m above the top of the spring. Find the maximum distance the spring will be compressed. 1.0 kg h = 0.8 m
