A 65-g arrow is fired from a bow whose string exerts an average force of 200 N on the arrow over a distance of 80 cm. What is the speed of the arrow as it leaves the bow?
An 82 g arrow is fired from a bow whose string exerts an average force of 95 N on the arrow over a distance of 85 cm. What is the speed of the arrow as it leaves the bow? Express as m/s
12) An 85 g arrow is fired from a bow whose string exerts an average force of 105 N on the arrow over a distance of 75 cm. What is the speed of the arrow as it leaves the bow? 8 A) 40.0 m/s B) 43.0 m/s C) 45.5 m/s D) 50.2 m/s E) 39.4 m/s
A 200 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 35 m/s2 for 31 s, then runs out of fuel. Ignore any air resistance effects. What is the rocket's maximum altitude? How long is the rocket in the air before hitting the ground? Express your answer with the appropriate units.
You throw a ball straight up. The ball has an initial speed of 11.2 m/s when it leaves your hand. A) What is the maximum height the ball reaches relative to the throwing point. B) How long does it take the ball to reach this height? C) What is the position of the ball at t=2s? D) At what height does the ball have a speed of +5m/s?
A ball is thrown straight up such that it leaves your hand with 200 Joules of kinetic energy. Suppose we choose the ball + Earth as our system and we use the height of the ball when it leaves your hand as h = 0. Answer the questions below ignoring air resistance. Initial gravitational potential energy when the ball leaves your hand = Kinetic energy when the ball is half way to its maximum height = j. Gravitational potential energy...
A cannon is fired at 52 degrees above the horizontal. The cannonball leaves the cannon at 85 m/s and reaches a maximum height h. At what initial velocity would the cannonball need to be fired to reach the same height if it were fired straight up?
An archer practicing with an arrow bow shoots an arrow straight up two times. The first time the initial speed is v0 and second time he increases the initial sped to 4v0. How would you compare the maximum height in the second trial to that in the first trial? A. Two times greater B. Four times greater C. Eight times greater D. Sixteen times greater E. The same
iPad 3:59 PM * 48%. 115:33:08 Exit 1 A rifle is fired straight up, and the bullet leaves the rifle with an initial velocity magnitude of 525 m/s. After 4.15 s, the velocity is 482 m/s. At what rate (in m/s2) is the bullet decelerated? (Recall that a negative sign denotes negative acceleration, or deceleration.) Enter answer 2 A rock thrown straight up climbs for 3.50 s, then falls to the ground. Neglecting air resistance, with what velocity (in m/s)...
mp/1198965-154704032318 015 (part 1 of 2) 10.0 points The speed of an arrow fired from a compound bow is about 23 m/s. An archer sits astride his horse and launches an arrow into the air elevating the bow at an angle of 49° above the horizontal and 1.7 m above the ground. 1.7 m range What is the arrow's range? The acceler- ation of gravity is 9.81 m/s. Assume the ground is leveland ignore air resistance. Answer in units of...
