PHY2048 Unit 2 Assignment Show all your steps and draw diagrams where necessary. Add explanatory notes where necessary. 1. A 2.0 kg ball is attached to a vertical post with two strings, one 2.0 m long and the other 1.0 m long as shown in the figure. If the ball is set whirling in a horizontal circle, what is the minimum speed necessary for the lower string to be taught? If the ball has a constant speed of 6 ms -1 , find the tension on each string. 2. At the end of a factory production line, boxes start from rest and slide down a 30 o ramp 5.4 m long. If the slide is to take no more than 3.3 s, what is the maximum coefficient of friction between the box and the slide?
