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...

A quarterback is set up to throw the football to a receiver who is running with a constant velocity ~vr directly away from the quarterback and is now a distance D away from the quarterback. The quarterback estimates that the ball must be thrown at an angle θ to the horizontal and the receiver must catch the ball a time interval tc after it is thrown. Assume the ball is thrown and caught at the same height y = 0...

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,...
