What is the shortest fm wavelength : A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
Estimate the work done on him by air resistance as he fell : A paratrooper pilot fell 360 m after jumping without his parachute opening. He landed in a snow bank, creating a crater 1.50 m deep, but survived with only minor injuries. Assume the pilot's mass was 80 kg and his terminal velocity was 50 m/s.

What is the change in its linear momentum : A new circus act is called the Texas Tumblers. Lovely Mary Belle swings from a trapeze, projects herself at an angle of 53, and is supposed to be caught by Joe Bob, whose hands are 6.10 above and 8.02 horizontally from her launch point. You can ignor..
If the mass of the butterfly is 12 g, at what acceleration : Two wires, each 28.15 cm long, are connected to two separate 9.00 V batteries as shown in the figure. The resistance of the first wire is 5.00 Ω, and that of other wire is unknown (R). If the separation between the wires is 4.55 mm, what value of R w..
Assume the blocks are equal length : A dam is used to block the passage of a river and to generate electricity. Approximately 5.73 x 10^4 kg of water fall each second through a height of 19.6 m. I one half of the gravitational potential energy of water were converted to electrical energ..
What is the acceleration of the crate : A pump, submerged at the bottom of a well that is 34 m deep, is used to pump water uphill to the house that is 50 m above the top of the well, as shown above. All pressures are gauge pressures. Avoid the effects of friction, turbulence, and viscosity..
