A 69.0 kilogram base runner begins his slide into second base when he is moving at a speed of 3.9 m/s. The coefficient of friction between Earth and his clothes is 0.70. He slides thus that his speed is zero just as he reaches the base.
(a) Obtain how much mechanical energy is lost due to friction acting on the runner?
J
(b) Evaluate how far does he slide?
m
A beam of light is emitted in a pool of water from a depth of 64.0 cm. How far away, relative to the spot directly above it, must it strike the air-water interface in order that the light does not exit the water?
At one instant a bicyclist is 25m due east of a park's flagpole, going due south with a speed of 8 m/s. Then, 11 s later, the cyclist is 65m due north of flagpole, going due east with a speed of 10 m/s.
a an energetic photon of wavelength 5.1 nm scatters off an electron at rest at an angle of 63 degrees. what is the
An energy-efficient lightbulb, taking in 23.0 W of power, can produce the same level of brightness as a conventional lightbulb operating at power 100 W. The lifetime of the energy-efficient bulb is 10 000 h and its purchase price is $4.00, whereas..
A certain lightbulb has a tungsten filament having a resistance of18 Ω at 25°C and 150 Ω whenhot. Assume R = R0[1 +α(T - T0)] can be usedover the large temperature range here. Find the temperature of the filament when it is hot.
