A battleship simultaneously fires two shells toward two identical enemy ships. One shell hits ship A, which is close by, and the other hits ship B, which is farther away. The two shells are fired at the same speed. Assume that air resistance is negligible and that the magnitude of the acceleration due to gravity is g. * What shape is the trajectory (graph of y vs. x) of the shells? a.straight line b.parabola c.hyperbola d. The shape cannot be...

5. The velocity of a projectile at its highest point is always b Positive a Negative c Zero d Equal to the initial velocity 6. If a projectile is launched with an initial velocity of 20 m/s from a height of 50 m in the direction 60° east of north, how long does it take the projectile to return to its original height? 彐 7. Peterson traveled 5 m due west, and then another 5 m due north. From his...

You are flying your personal rocket craft at 0.9 c from Star A to Star B. The distance between the stars, in the stars’ reference frame is 1.0 ly. Both stars happen to explode simultaneously in your reference frame at the instant you are exactly halfway between them. (a) Do you see the flashes simultaneously? If you do, explain how. If you do not, which flash do you see first and what is the time difference between the two flashes?...
