Question 1, chap 8, sect 1. part 1 of 1 10 points A 6 kg mass is attached to a light cord that passes over a massless, frictionless pulley. The other end of the cord is attached to a 2 . 2 kg mass. The acceleration of gravity is 9 . 8 m / s 2 . 7 . 2 m ω 6 kg 2 . 2 kg Use conservation of energy to determine the final speed of the first mass after it has fallen (starting from rest) 7 . 2 m. Answer in units of m / s. Question 2, chap 8, sect 1. part 1 of 3 10 points A block starts at rest and slides down a fric- tionless track (as shown in the figure below). It leaves the track horizontally, flies through the air, and subsequently strikes the ground. The acceleration of gravity is 9 . 81 m / s 2 . b b b b b b b b b b b b 591 g 4 . 2m 2 . 2m x 9 . 81m / s 2 v What is the speed v of the ball when it leaves the track? Answer in units of m / s. Question 3, chap 8, sect 1. part 2 of 3 10 points What is the horizontal distance x the block travels in the air? Answer in units of m.
