The plane’s horizontal veloc- ity was 133 m / s at the instant the hamper was dropped. The acceleration of gravity is 9 . 8 m / s 2 . What is the magnitude of the overall veloc- ity of the hamper at the instant it strikes the surface of the ocean? Answer in units of m / s. 002 (part 1 of 2) 10.0 points The speed of an arrow fired from a compound bow is about 82 m / s. An archer sits astride his horse and launches an arrow into the air, elevating the bow at an angle of 64 ◦ above the horizontal and 2 . 3 m above the ground.
