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?
Homework Answers
From kinematic equation
Vy= V0y + ay*t
at maximum height Vy=0,
0= V0y +(-g)*t
t =V0y/g------1
For maximum height,s =V0y*t +1/2*ay*t^2
put equation 1 in above and get maximum height

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 on a cliff at a height of H = 34 meters fires a cannonball in the horizontal direction. The initial velocity of the cannonball is 6.9 m/s. What is the horizontal distance D which the cannonball travels before it hits the ground below? What will the speed of the ball be just before it hits the ground? What direction will the cannonball be moving just before it hits the ground? Enter the angle relative to the horizontal axis....

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.
