The answers I got were 17589.2, 56250 (both correct) and -4.69x10^11 & -1.14 x 10^11 (both incorrect)

A 21.0-kg cannonball is fired from a cannon with muzzle speed of 1 050 m/s at an angle of 34.0° with the horizontal. A second ball is fired with the same initial speed at an angle of 90.0°. Let y = 0 at the cannon.

Basic Physics: Projectile Motion. 1. Given that a ball is launched perfectly horizontally from a height of 1.2 meters, and lands on the floor a horizontal distance of 2.6 meters away, find the initial speed (or "muzzle velocity") of the ball in meters per second. Use 9.82 meters per second for "g". 2. A ball is launched at an angle of 56.5 degrees up from the horizontal, with a muzzle velocity of 7 meters per second, from a launch point...

Missed 6 questions. I got 10 correct. The answers I got wrong are: Goodwill for both blanks 90,000 and 90,000, Total assets 5,335,000, Liabilities 45,000 and -45,000 and for the second blank under liabilities I tried 835,000. For total liabilities and stockholders equity, I answered 5,335,000 which are all wrong.   Constructing the Consolidated Balance Sheet at Acquisition On January 1 of the current year, Healy Company purchased all of the common shares of Miller Company for $500,000 cash.

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...
