A block with a mass of 2.50 kg on a spring has displacement as afunction of time given by the equationx(t)= (7.9 cm) cos [5.5 rad/s) t - 2.42 rad].
Part A: what is maximum kinetic energy during oscillation?(.......J)
Part B: what is the velocity of block at t = 2.3 s ?(.....m/s)
Part C: if kinetic energy and potential energy are equal, whatis the positive value of the displacement? (X=.....cm)
