What is the mass of a baseball if the kinetic energy is 140 j when the baseball is thrown at 96 mph? 0.021 g a batter hits a pop fly, and the baseball reaches an altitude of 270 ft. if we assume that the ball was 3 ft. above home plate when hit by the batter, what is the ball's increase in potential energy? j

What are the phases shown in a and d called?

Which of the following is the phase that results when the moon is on the opposite side of the earth from the sun? a. quarter moon b. crescent moon c. new moon d. full moon

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
