Reset the cannon.


2. Change the angle of the cannon to 60º and set the initial speed to 15 m/s.


3. Unclick “acceleration vectors and click the “components” and “velocity vectors” in the right box.


4. Pause the simulation at any point during the time when the ball is in air, take a screenshot and paste it below.






5. How does the length of velocity vector in the y direction change as the ball moves in the air? Explain.




6. When is the velocity vector in the y direction 0?






7. Does the length of velocity vector in the x direction change as the ball moves in the air? Explain.

Change the Gravity to 9.80 m/s2.. Keep the height of the cannon at ground level. Determine what angles you must have the cannon tilted at to have the cannon ball land at the target 20.5 m away when you have an initial speed of 20 m/s using the simulation. Let the mass of the cannon ball remain at 17.60 kg and the diameter at 0.18 m. Then use the Range formula R=v02sin(2θ)g to verify the angles. (Hint: recall from Trigonometry...

You throw a tennis ball North with an initial speed of 24 feet per second, at an angle of elevation 30° above horizontal, releasing the ball 4 feet above the ground. A steady wind imparts a constant acceleration of 3 feet per second squared Eastward. Acceleration due to gravity is a constant 32 feet per second squared downward. Throughout the problem, let East be the positive x direction, North the positive y direction, and up the positive z direction. Let...

1. For a stationary ball of mass m = 0.200 kg hanging from a massless string, draw arrows (click on the “Shapes” tab) showing the forces acting on the ball (lengths can be arbitrary, but get the relative lengths of each force roughly correct). For this case of zero acceleration, use Newton’s 2nd law to find the magnitude of the tension force in the string, in units of Newtons. Since we will be considering motion in the horizontal xy plane,...

A restored Civil War cannon is being tested using cannonballs of various mass and using various loads of gunpowder. In one test, the cannon fires a cannonball at a speed of 74.0  m/s in a direction which is 51.0  degrees Up from East. The cannonball is intended to land on a mesa which is to the east of the cannon. The near edge of the mesa is a vertical cliff which is 103.0  m high; the base of the cliff is 127.0  m to...
