It is due by 06:00 AM Abu Dhabi Time on Tuesday 11 March(8:00 PM Monday March 10, Texas time) 001 (part 1 of 1) 5 points A 3 . 37 kg block is released from A at height 4 . 72 m on a frictionless track shown. The radius of the track is 2 . 19 m. The acceleration of gravity is 9 . 8 m / s 2 . R P A h Determine the magnitude of the accelera tion for the block at P. Answer in units of m / s 2 . 002 (part 1 of 1) 5 points A 33 g block is released from rest and slides down a frictionless track that begins 3 m above the horizontal, as shown in the figure. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a spring constant of 18 N / m. The acceleration of gravity is 9 . 8 m / s 2 . 3 m 33 g 18 N / m Find the maximum distance the spring is compressed. Answer in units of m. 003 (part 1 of 2) 5 points Apendulumconsistsofasphereofmass1 . 5kg attached to a light cord of length 10 . 2 m as in the figure below. The sphere is released from rest when the cord makes a 34 ◦ angle with the vertical, and the pivot at P is frictionless....
