An 94-g arrow is fired from a bow whose string exerts an average force of 130 N on the arrow over a distance of 74 cm . Part A What is the speed of the arrow as it leaves the bow? Express your answer to two significant figures and include the appropriate units.
030 (part 1 of 4) 10.0 points Two students are on a balcony 20.7 m above the street. One student throws a ball ver- tically downward at 14.6 m/s. At the same instant, the other student throws a ball verti- cally upward at the same speed. The second ball just misses the balcony on the way down. What is the magnitude of the velocity of the first ball as it strikes the ground? Answer in units of m/s. 031 (part...
An 150 gram arrow is fired straight up with an acceleration of 200 m/s 2 a) What force is applied to the arrow? b) IF the arrow leaves the bow at a speed at 50 m/s determine the maximum height the arrow reaches? c) If the bow accelerates the arrow for 0.25s. How far did the arrow move during that time? Is this a reasonable number (why or why not)?
