Acat leaps to catch a bird. if the cat's jump was at 60.0° angle off the ground with a velocity of 5.75 m/s. (a) what the cat's maximum height above the ground? (b) how much time does the cat spend in the air before landing on the ground again ?
Aone third -kg mass is attached to a spring with stiffness 75 n/m. the damping constant for the system is 6 n-sec/m. if the mass is moved startfraction 12 over 5 endfraction m to the left of equilibrium and given an initial rightward velocity of startfraction 48 over 5 endfraction m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod, and quasifrequency.
