A small rubber ball is launched by a compressed-air cannon from ground level with an initial speed of 18.2 m/s directly upward. Choose upward as the positive direction in your analysis. (a) What is the maximum height above the ground that the ball reaches? 0 x What is the final velocity, momentarily, at the highest point? Knowing this, and the given information, can you use a constant acceleration kinematic relation to find the height? Also, be careful of signs. What...

A ball is launched from the top of a building 80 m high at an angle of above the horizontal with a speed of 63 in/s. How long does it take before the ball reaches its highest point? What is the maximum height of the ball above the ground? How long is the ball in the air before it hits the ground? How far does the ball travel horizontally before it hits the ground? What is the acceleration of the...
A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...
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 tilted at 25" above the horizontal is fired from the top of a cliff 100 m exits the cannon at a speed of 150 m/s. The ground below is flat. tall. The ball Wh at is the highest point above the ground the ball will reach? What is the speed of the ball at the highest point? How long does it take the ball to reach the ground? How far horizontally will the ball have traveled when it...
