Unformatted text preview: mohammed (omm269) – OH06 – bradley – (19101) 1 This printout should have 17 questions. Multiplechoice questions may continue on the next column or page – find all choices before answering. This is Online Homework No. 6 (OH06). All answers should be submitted online be fore 2300 on Tuesday 8 March (UAE time). Computers and network connections can give trouble, so do not wait until the last minute! 001 10.0 points A 8 kg object attached to a horizontal string moves with constant speed in a circle on a frictionless horizontal surface. The kinetic energy of the object is 60 J and the tension in the string is 318 N. Find the radius of the circle. Answer in units of m. 002 10.0 points A 2 . 8 kg block is pushed 1 . 34 m up a vertical wall with constant speed by a constant force of magnitude F applied at an angle of 60 . 4 ◦ with the horizontal. The acceleration of gravity is 9 . 8 m / s 2 . 2 . 8 kg F 6 . 4 ◦ If the coefficient of kinetic friction between the block and wall is 0 . 561, find the work done by F ....
