A block of mass m = 2 kg is attached to a spring with spring constant k = 200
N/m, and is set to oscillate on a friction-less horizontal surface. At time t = 0 its
position is X0 = 0 and its velocity is v0 = +5 m/s. If the displacement is a cosine
function, X(t)=A cos(wt+p), then which answer is correct about the oscillation
amplitude A and the phase constant, p.:

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?
