Baling HayPro Problems > Physics > Motion and Forces > Projectile Motion
A hay baler shoots bales of hay out at a 30 degree angle. The bale of hay rises to a height of 3 feet above its launch position before it begins to fall. How far did the bale travel horizontally in that time?
SolutionIn order to make it feasible for teachers to use these problems in their classwork, no solutions are publicly visible, so students cannot simply look up the answers. If you would like to view the solutions to these problems, you must have a Virtual Classroom subscription.
A slingshot is two meters off the ground. The ammunition is in contact with the slingshot for 0.02 seconds during launch. The ammunition is fired horizontally, and lands 12 meters from the launch point. If the ammunition has a mass of 0.5 kg, what was the force applied to the ammunition during launch?
Because of union troubles at the North Pole, Santa has to cut corners in his operation. One of the ways he's cutting corners this year is as follows: at every house, he will swoop down to 0.5 meter above the top of each chimney, and just as he's passing over the edge of the roof, he will drop presents from his sleigh, so they will fall down the chimney.
This will save him the time and trouble of climbing down chimneys (plus, Mrs. Claus likes it because he doesn't have as much cookies and milk this way).However, there is a problem with the new system. Everyone's chimney must be the same distance from the edge of the roof. If Santa's sleigh travels at 40
A bullet is fired horizontally from a gun with an initial velocity of 600 ft/s. Wind resistance causes a horizontal acceleration of -2 ft/s2. If the bullet is 4 feet off the ground when it is fired, how far will it travel before striking the ground?
A roof has a slope of 20 degrees, and a length of 20 meters. A box slides down the roof from the peak (assume a coefficient of kinetic friction of 0.15), until it reaches the edge of the roof. At this point, it falls 10 meters to the ground. How far from the building will the box land?
A cannon is placed at the edge of the deck of a battleship, nearest to the enemy’s warship. A projectile is fired toward the enemy, whose deck is at the same height as the first ship’s deck. The enemy ship is 500 feet away, and the ship is 50 feet wide. The muzzle velocity of the cannon is 400 ft/s. What range of angles can be used, and have the projectile hit the enemy battleship's deck?
BONUS: What can we conclude about the height at which the ping pong balls were fired?* 16
A cannonball is fired from a cannon, at a height of 3 feet from the ground.
The cannonball travels 80 yards before hitting the ground. At what speed is the cannonball traveling when it hits the ground?
