Question

Two identical strings making an angle of e 30.0° with respect to the vertical support a block of mass m-15.0 kg. What is the tension in each of the strings? 1 A 75-kg man standing on a scale in an clevator notes that as the elevator rises, the scale reads 825 N What is the acceleration of the elevator? 2. 3. A 150-N bird feeder is supported by three cables as shown in the figure. Find tension in each cable 60 30 Bird food 4. A crate of mass m - 32 kg rides on the bed of a truck attached by a cord to the back of the cab as in the figure. The cord can withstand a maximum tension of 68 N before breaking. Neglecting friction between the crate and truck bed, find the maximum acceleration the truck can have before the cord breaks.
