019 10.0 points A cannon fires a 0.579 kg shell with initial velocity Vi-11 m/s in the direction θ 43° above the horizontal. The shell's trajectory curves downward be- cause of gravity, so at the timet 0.55 s the shell is below the straight line by some vertical distance ΔΙι Find this distance Ah in the absence of air resistance. The acceleration of gravity is 9.8 m/s2. Answer in units of m

A dynamite blast at a quarry launches a rock straight upward, and 1.8 s later it is rising at a rate of 12 m/s. Assuming air resistance has no effect on the rock, calculate its speed (a) at launch and (b) 5.4 s after launch.

A cannon tilted upward at θ = 28.7 ∘ fires a cannonball with a speed of 92.5 m/s on level ground. Part D At what time after being fired does the cannonball reach it's maximum height above the ground? Part E What is the distance that the cannonball travels horizontally before reaching the ground again (assuming it was shot at exactly ground level with the velocity given)?

A ball is launched directly upward from ground level with an initial speed of 22 m/s. (Air resistance is negligible) How long is the bail in the air? 4.486s What ls the greatest height reached by the ball? 24.7m How many seconds after launch is the ball 6 m above the release point? s after being thrown (first time) s after being thrown (second time)
A cannon tilted upward at θ = 30 ∘ fires a cannonball with a speed of...
A cannon tilted upward at θ = 30 ∘ fires a cannonball with a speed of 95 m/s . At that instant, what is the component of the cannonball’s velocity parallel to the ground?

A cannon that is aim 60 degree above the horizon fires at a object that is 1000m downrange and moving away from the cannon at 20 m/s. How fast does the shell have to leave the cannon in order to hit the object? At what position from the cannon does shell hit the target?

A ball is launched directly upward from ground level with an initial speed of 22 m/s. (Air resistance is negligible.) (a) How long is the ball in the air? 220/49 S (b) What is the greatest height reached by the ball? 1000149xm (c) How many seconds after launch is the ball 5 m above the release point? s after being thrown (first time) s after being thrown (second time) Be careful when assigning signs to the kinematic quantities.

A cannon shell is fired on a flat surface and it is found that the shell is in the air for 2.78 s and reaches a distance of 94.7 m. What was the initial Launch angle and speed? In an airport moving walkways help get passengers to their gates faster. In one case a person stands on the walkway and arrives at the gate in 525 seconds. Another time the walkway is broken and he makes the same trip in...

A dynamite blast at a quarry launches a rock straight upward, and 2.1 s later it is rising at a rate of 11 m/s. Assuming air resistance has no effect on the rock, calculate its speed (a) at launch and (b) 4.8 s after launch.

A dynamite blast at a quarry launches a rock straight upward, and 2.4 s later it is rising at a rate of 15 m/s. Assuming air resistance has no effect on the rock, calculate its speed (a) at launch and (b) 4.6 s after launch.
