A block with a mass of 2.50 kg on a spring has displacement as a
function of time given by the equation
x(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, what is the positive value of the displacement? (X=.....cm)
