Q. Fairgoers ride a Ferris wheel with a radius of 5. The wheel completes one revolution every 33.
a) What is the average speed of a rider on this Ferris wheel?
b) If a rider accidentally drops a stuffed animal at the top of the wheel, where does it land relative to the base of the ride? (Note: The bottom of the wheel is 1.75 above the ground.)
A 251 kg wooden raft floats on a lake. When a 70kg man stands on the raft, it sinks 4cm deeper into the water. When he steps off, the raft vibrates for a while.
An airplane flies 200 km due west from city A to city B and then 315 km in the direction of 33.0° north of west from city B to city C.
A stunt pilot performs a circular dive of radius 715m. At the bottom of the dive pilot has a speed of 265 m/s which at that instant is increasing at a rate of 15 m/s2(along the direction of vector B) What total acceleration does the pilot have at ..
A boat moves relative to water with a velocity which is n =2 times less than the river flow velocity. At what angle to the stream direction should the boat move to minimize drifting.
A flower pot fell of a windowsill and falls past the window below. you may ignore air resistance. it takes the pot .470s to pass the window, which is 1.80m hight. how far is the top of window below the windowsill from w/c the flower pot fell.
A mass spectrometer applies a voltage of 2 kV to accelerate a singly charged positive ion. A magnetic field of B = 0.400 T then bends the ion into a circular path of radius 0.305m. What is the mass of the ion.
A certain particle has the life time of 10^-7 s, while measured at rest. How far does it go before decaying if its speed is 0.99 c when it is created.
what volume should the balloon have after being inflated. Billiard ball A of mass mA=0.400kg moving with speed vA=1.80m/s strikes ball B, initially at rest of mass mB=0.500kg. As a result of collision, ball A is deflected off at an angle of 30.0 deg..
A plot of pressure as a function of volume is known as a pV diagram. pV diagrams are often used in analyzing thermodynamic processes. Consider an ideal gas that starts in state O, as indicated in the diagram. Your task is to explain how the gas proce..
