A meteor falls from the sky to the earth. The meteor already had an initial velocity downward shen it was spotted. If it high earth at 335 m/s after being seen for 30 seconds, then what is the initial velocity of the meteor? The meteor accelerates at 10 m/s squared.

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.
