Projectile Motion In Exercises 27-40, use the model for projectile motion, assuming there is no air resistance and
A bale ejector consists of two variable-speed belts at the end of a baler. Its purpose is to toss bales into a trailing wagon. In loading the back of a wagon, a bale must be thrown to a position 8 feet above and 16 feet behind the ejector.
(a) Find the minimum initial speed of the bale and the corresponding angle at which it must be ejected from the baler.
(b) The ejector has a fixed angle of

- In which direction clockwise or counterclockwise will pulley 1 rotate if pulley 2 rotates in the clockwise direction? a barrow_forwardForce Tyler and his cousin Kelly have attached a rope to the branch of a tree and tied a board to the other end to form a swing. Tyler sits on the board while his cousin pushes him through an angle of 25.5 and holds him there. If Tyler weighs 95.5 pounds, find the magnitude of the force Kelly must push with horizontally to keep Tyler in static equilibrium. See Figure 1.
