In the figure above, an object of mass M = 2.1 kg is dropped from a distance h = 0.43 meter above an uncompressed spring. The spring has a constant of k = 210 N/m. The object becomes attached to the spring upon collision.
(a) Calculate the speed of the object when it collides with the spring.
(b) Determine how far the spring has moved when the object reaches maximum speed.
(c) On the grid below make a graph of the acceleration a of the block as a function of time t for two oscillations. The horizontal axis is scaled for the values of time T and 2T where T is the period of oscillation. Let t = 0 when the object is at its lowest position.
(d) On the grid below make a graph of the kinetic energy K of the block as a function of time t for two oscillations. The horizontal axis is scaled for the values of time T and 2T where T is the period of oscillation. Let t = 0 when the object is at its lowest position.
(e) Describe how the period of oscillation of the object could be changed to one-half its current value. Explain your reasoning.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

The vapour pressure of benzene is 53.3 kpa at 60.6 °c, but it fell to 51.5 kpa when 19.0 g of a non-volatile organic compound was dissolved in 500 g of benzene. calculate the molar mass of the compound.
