An airplane is dropping bales of hay to cattle stranded in a blizzard on the Great Plains. The pilot releases the bales at 180 m. above the level ground when the plane is flying at 70.0m/s. 60.0 degrees above the horizontal. How far in front of the cattle should the pilot release the hay so that the bales will land at the point where the cattle are stranded?
An atomic nucleus of mass m travelling with speed v collides elastically with a target particle of mass 2.000m (at first at rest) and is scattered at 90.
A gymnast of mass 60kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 for the acceleration of gravity.
Two forces FA and FB are applied to an object whose mass is 5.43 kg. The larger force is FA. When both forces point due east, the object's acceleration has the magnitude of 1.40 m/s2. Though, as FA points due east and FB points due west, the accelera..
Two automobiles of equal mass approach an intersection. One vehicle is travelling with velocity 13 m/s toward the east and the other is travelling north with speed v2i. Neither driver sees the other.
Assume it takes 8.00 min to fill a 25.0-gal gasoline tank. (1 U.S. gal = 231 in.3) (a) Calculate the rate at which the tank is filled in gallons per second. (Please provide numerical answer in gal/s)
A particle of mass m is attracted to a force center with force of magnitude k/r2. Use plane ploar coordinates and find Hamilton's equations of motion.
A car is traveling along a straight road at a velocity of +31.0 m/s when its engine cuts out. For the next ten seconds, the car slows down, and its average acceleration is a1.
How several 90-rm W, 120-rm V light bulbs can be connected to a 20-rm A, 120-rm V circuit without tripping the circuit breaker.
imagine the water is in freefall as it drops. What charge must be on each plate.
A pair of oppositely charged parallel plates are separated by a distance of 5 cm with a potential difference of 550 V between the plates. A proton is released from rest at the positive plate at the equal time that an electron is released from rest..
This situation is like that of a car on a curve that is banked at an angle of 21.50°. If she tries to make the turn without slowing down, what is the minimum distance from the seawall that she can begin making her turn and still keep away from a c..
