    A cannon fires a ball horizontally with a velocity of 240 m/s. If the cannon is in a 44 meter tall tower and the ground below is flat, then (a) How long does the ball take to hit the ground after being fired? (b) At what horizontal distance from the cannon does the ball hit the ground? and (c) What are the horizontal and vertical components of the ball's velocity just before it hits the ground?

    a cannon ball was fired from a cannon on level ground. an observer in a balloon observed the top of the ball’s flight. as the ball barely misses the observer, he measures a speed of 111 m/s and a height of 75.2 m. how far (horizontally) from the balloon does the ball land? from where was it fired? at what angle was the cannon fired?

    A cannon ball is fired horizontally with an initial velocity of 50 m/s. If it takes 5 seconds for the ball to fall to the ground, how large of a horizontal distance did it travel?

  • A cannon is fired over level ground at an angle of 30 degrees to the horizontal....

    A cannon is fired over level ground at an angle of 30 degrees to the horizontal. the initial velocity of the cannonball is 400 m/s but because the cannon is fired at an angle, the vertical component of the velocity is 200 m/s and the horizontal component is 346 m/s a. How long is the cannonball in the air (use 10 m/s^2 and the fact thatthe total time of flight is twice the time required to reach the high point.

    2. (a) A ball is fired from a cannon straight up at a velocity of 30ms^ - 1. The ball leaves the cannon at a height of 5 m that is vertically above the ground. Find the time taken until the ball hits the ground. Find the velocity of the ball when it hits the ground. If the ball had been projected at 10 ms^ - 1 instead of 30 ms^ - 1, what would its final velocity when it...

    Problem C) A cannon ball is shot up from ground level to the top of a tower which is 200 m away and 150 m high as shown in the figure below. If the cannon ball hits the top of the tower 6.5 s after it was fired, what was the initial velocity of the cannon ball (magnitude and direction) ignoring air resistance.

    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 23.0 kg cannon ball is fired from a cannon with a muzzle speed of 1100 m/s at an angle of 32.0° with the horizontal. A second ball is fired at an angle of 90.0°. a.) Use the conservation of energy principle to find the maximum height reached by each ball b.) What is the total mechanical energy at the maximum height for each ball? Let y = 0 at the cannon
