A cannon is fired horizontally. Before the firing, the cannon (which is mounted on a massive...
7. Figure 4 shows a cannon. When the gun is fired, high pressure gasses accelerate the projectile. The reaction force pushes the gun barrel in the opposite direction to the projectile. The gun barrel is made to translate backwards against a critically damped spring-damper system called the recoil mechanism. The mass of the gun barrel the recoi mechanism is 500 kg and the recoil spring stiffness is 10 kN/m. Upon firing, the gun recoils 0.4 m. Find (a) the damping...
Q6 A projectile is fired horizontally from a gun that is 45.0 m above flat ground, emerging from the gun with a speed of 250 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? [3+2]
Your dorm wishes to purchase a small used cannon with the intent of firing a blank after each touchdown at home games. The spec sheet for a cannon of interest is missing some pages; however, the information you have claims that when the cannon is fired, the position of the cannonball as a function of time (while it is in the barrel of the cannon) is given by x(t) = (1.50 ✕ 105 m/s2)t2 − (1.20 ✕ 107 m/s3)t3. The...
A projectile is fired horizontally from a gun that is 66.0 m above flat ground, emerging from the gun with a speed of 250 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? m (c) What is the magnitude of the vertical component of its velocity as it strikes the ground? m/s
Q4. A cannon mounted on wheels has a mass of 1380 kg. It shoots a 5.45-kg shell at 190 m/s lforward]. What will be the velocity of the cannon immediately after firing the shelr? (Read Examole9.5 on textbook)
A projectile is fired horizontally from a gun that is 32.0 m above flat ground, emerging from the gun with a speed of 300 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? (c) What is the magnitude of the vertical component of its velocity as it strikes the ground?
need speed as well
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...
