1. During a rockslide, a 520 kg rock slides from rest down a hillside that is 500m long and 300m high. The coefficient of kinetic friction between the rock and the hill surface is 0.25 (a) If the gravitational potential energy U of the rock-Earth system is zero at the bottom of the hill, what is the value of U just before the slide? (b) How much energy is transferred to thermal energy during the slide? (c) What is the kinetic energy of the rock as it reaches the bottom of the hill? (d) What is its speed then? 2. A worker pushed a 27kg block 9.2m block along a level floor at constant speed with a force directed 32degrees below the horizontal. If the coefficient of kinetic friction be... click for more

1. For an incoming ray of light of vacuum wavelength 589 nm, fill in the unknown values in the following table. from(medium) to(medium) 0i 0r ---------------------------------------------------- a. flint glass crown glass 25.0 ? b. air ? 14.5 9.80 c. air diamond 31.6 ? 2. The smallest insects that a bat can detect are approximately the size of one wavelength of the sound the bat makes. What is the minimum frequency of sound waves required for the bat to detect an insect that is 0.57 cm long? (Assume the speed of sound is 340 m/s.)
