A 1.50 kg water balloon is shot straight up with an initialspeed of 5.00 m/s.
(a) What is the kinetic energy of the balloon just asit is launched?
J
(b) How much work does the weight of the balloon do on the balloonduring the balloon's full ascent?
(c) What is the change in the gravitational potential energy of theballoon Earth system during the full ascent?
(d) If the gravitational potential energy is taken to be zero atthe launch point, what is its value when the balloon reaches itsmaximum height?
(e) If, instead, the gravitational potential energy is taken to bezero at the maximum height, what is its value at the launchpoint?
(f) What is the maximum height of the balloon?
m
A solid marble, a solid disk and a hoop have the same mass (M = 0.9 kg) and the same radius. Each object is held at rest at the same height and then released. what is the force the track exerts on the disk when released at the minimum height
An object of mass "m" is thrown up an inclined plane of angle "theta" with an initial velocity "v knot". If the motion is resisted by retarding force Fr=-kv (where k is a force coefficient and v the velocity of the object.)
The fundamental frequency of an open organ pipe corresponds to the middle C (261.6 Hz on the chromatic musical scale). The third resonance of a closed organ pipe has the same frequency. (Assume that the speed of sound in air is 343 m/s.) What is the ..

A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 35.0 degrees below the horizontal. estimate the length of time the car is in the air
Artificial gravity. One way to create artificial gravity in a space station is to spin it. If a cylindrical space station 275 m in diameter is to spin about its central axis, at how many revolutions per minute (rpm) must it turn so that the outermost..
