Unformatted text preview: homework 02 GADHIA, TEJAS Due: Jan 31 2007, 4:00 am 1 Question 1 part 1 of 2 10 points The tallest volcano in the solar system is the 24 km tall Martian volcano, Olympus Mons. Assume: An astronaut drops a ball off the rim of the crater and that the free fall acceler- ation of the ball remains constant throughout the balls 24 km fall at a value of 3 . 2 m / s 2 . (We assume that the crater is as deep as the volcano is tall, which is not usually the case in nature.) a) Find the time for the ball to reach the crater floor. Answer in units of s. Question 2 part 2 of 2 10 points b) Find the magnitude of the velocity with which the ball hits the crater floor. Answer in units of m / s. Question 3 part 1 of 1 10 points A stone is thrown straight up- ward and at the top of its trajec- tory its velocity is momentarily zero. What is its acceleration at this point? 1. Zero 2. 9.8 m/s 2 up 3. 9.8 m/s 2 down 4. Unable to determine Question 4 part 1 of 1 10 points The acceleration due to gravity on planet X is one fifth that on the surface of the earth. If it takes 4 . 2 s for an object to fall a certain distance from rest on earth, how long would it take to fall the same distance on planet X?...
