1) what is the acceleration due to gravity On the planet where an 84 cm pendulum requires 293.9 seconds to swing 74 times? 2) The speed of sound in air is measured to be 330.1 m/s the frequency of a sound emitted by a source moving away from you is found to be 292 Hz. if the frequency of the sound at this source is actually 366 hz, then the speed of the source is ____m/s? 3) An astronaut stands on the edge of a lunar crater and throws a half eaten Twinkie horizontally with a velocity of 25 m/s the floor of the crater is 326.2 m Below the astronaut. What horizontal distance will the Twinkie travel, in m, before hitting the floor of the creater? ( the acceleration off gravity on the moon is 1/6 that of earth)
