A block is attached to a spring with a sping constant of 7.6 N/m and it undergoes simple harmonic motion.  The amplitude of the blocks motion is 6.30 cm. When the block is halfway between its equilibrium position and the end point of it's motion, its speed is measured to be 28.9 cm/s. Calculate : (a) the mass of the block, (b) the period of the motion, and (c) the maximum acceleration of the block.

A block of unknown mass is attached to a spring with a force constant of 6.50 N/m and undergoes simple harmonic motion with an amplitude of 10.0 cm.

A spring is compressed by 0.0610 m and is used to launch an object horizontally with a speed of 2.80 m/s. If the object were attached to the spring, at what angular frequency (in rad/s) would it oscillate?

A body with mass of 250 g is attached to the end of a spring that is stretched 25 cm by a force of 9 N. At time t=0 the body is pulled 1 m to the left. stretching the spring, and set in motion with an initial velocity of 5 m/s to the right. (a) Find x(t) in the form C cos (-a).

A mass of 8.0 kg hangs from a spring attached to the ceiling. The spring has a spring constant of 500 N/m and it stretches 15.7 cm from its mean position. A student grabs the spring, applies a force and stretches it a further 6.7 cm downwards. The block is released and initially accelerates upward before undergoing simple harmonic motion. Calculate the initial vertical acceleration of the mass. (Units: m/s? , to 2 sig figs)

A 200 g mass is attached to a spring with k = 60 N/m and allowed to oscillate with an amplitude of 0.12 m.  What is the maximum speed of the mass?

A 480-gg block on a frictionless surface is attached to a rather limp spring of constant k=8.7N/mk=8.7N/m. A second block rests on the first, and the whole system executes simple harmonic motion with a period of 1.2 ss . When the amplitude of the motion is increased to 35 cmcm, the upper block just begins to slip. What is the coefficient of static friction between the blocks?

The rotational inertia of a uniform thin rod about its end is ML2 /3, where M is the mass and L is the length. Such a rod is hung vertically from one end and set into small-amplitude oscillation. If L = 1.0 m, this rod will have the same period as a simple pendulum of length:   (a) 33 cm  (b) 50 cm  (c) 67 cm  (d) 100 cm  (e) 150 cm
