the time the cannonball spend in the air is the time of flight T = 2 u sinθ / g
where u is the initial velocity with which the ball is projected and θ is the angle of projection.
T = 2 x 10 x sin 45 / 9.8
T = 1.7365 seconds
A cannon is fired at 10m/s at an angle of 45 degrees. What is the time...
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 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.
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?
#1) A 40 kg cannonball is fired from a cannon at an angle of 28° with an initial velocity of 30 m / s. It lands a distance _____ m from its initial position. #2) A 40 kg cannonball is fired from a cannon at an angle of 28° with an initial velocity of 30 m / s. It is in the air for ____ s.
A cannonball is fired at 70.3 m/s from a cannon at an angle of 50∘ when measured from the horizontal as shown in the figure below. The cannon is firing up onto an elevated hillside that is 60 meters above the level of the cannon. Find the horizontal distance traveled to where the projectile strikes the ground.
A cannonball is fired at 65.3 m/s from a cannon at an angle of 50∘ when measured from the horizontal as shown in the figure below. The cannon is firing up onto an elevated hillside that is 60 meters above the level of the cannon. Find the horizontal distance traveled to where the projectile strikes the ground.
