A cannonball is fired from 15 m above the ground, with a speed of 40. m/s at an angle of 35.0◦ . (a) How long is the person in the air before hitting the ground? (b) What is their maxiumum height? (c) What was their total range? (Range refers to their final horizontal displacement)
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?
A cannonball is fired from the ground and lands on a hill as shown in the figure below: 35° 150 m The initial velocity of the cannonball as it exits the canon is 50 m/s and it is launched at an angle of 35 above the horizontal. The cannonball lands on the hillside 150 m away from the cannon in the horizontal direction (as shown). 2 pts - a) What are the x- and y-components of the initial velocity of...
A. A cannon is fired over level ground at an angle of 30 degrees to the horizontal. The initial velocity of the cannonball is 500 m/s but because the cannon is fired at an angle, the vertical component of the velocity is 250 m/s and the horizontal component is 433 m/s. How long is the cannonball in the air? (Use g = -10 m/s2) B. A cannon is fired over level ground at an angle of 30 degrees to the...
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. a. Determine the maximum height above the ground reached by the cannonball.b. What speed will the...
A cannon fires a cannonball at an angle of 30 degrees about horizontal. The initial velocity of the cannonball is 40 m/s. A) How long will it take the cannonball to reach maximum height B) What is the maximum height the cannonball will reach C) What distance in x will the cannonball travel before hitting the ground?
Mr. M is a human cannonball in his spare time. If the cannon he uses is1.75 meters long and he exits the cannon at a speed of 20.0 m/s, what acceleration does the cannon impart to Mr. M ?
a) A bullet is fired from a rifle pointed 45 degrees above horizontal. The bullet leaves the muzzle traveling 1400 m/s. How many seconds does it take the bullet to reach the high point of its trajectory? b) What is the bullet's height at the highest point? Express the answer in km. c) How far away from where the gun is fired does the bullet land? Answer in km.
1. Solve the following problem on a clean sheet of paper. A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. Landing point a. Deternine the...
King Arthur's knights fire a cannon from the top of the castle wall. The cannonball is fired at a speed of 47 m/s and an angle of 26°. A cannonball that was accidentally dropped hits the moat below in 1.06 s. A) How far from the castle wall does the cannonball hit the ground? B)What is the ball's maximum height above the ground?
