Aparticle oscillates harmonically x = a cos(ωt + φ0), with amplitude 9 m, angular frequency π s −1, and initial phase π 3 radians. every now and then, the particle’s kinetic energy and potential energy happen to be equal to each other (k = u). when does this equality happen for the first time after t = 0?

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.
