. The earth revolves around the sun in the counterclockwise direction, completing one full revolution about every 365 days. In reality the orbit is elliptical (with an eccentricity of 0.0167), but we’ll pretend that the orbit is a perfect circle. How many revolutions per day does the earth make around the sun? What is the angular velocity ωSE (radians/day) of the earth around the sun?

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
