2 Multiple Objects q A block of mass m1 on a ough, hoizontal suface is connected to a ball of mass m by a lightweight cod ove a lightweight, fictionless pulley as shown in figue. A foce of magnitude F at an angle with the hoizontal is applied to the block as shown and the block slides to the ight. The coefficient of kinetic fiction between the block and suface is μ k. Find the magnitude of acceleation of the two objects. Januay, 017

14 Example : The Effect of Speed on q Centipetal Foce The model aiplane has a mass of 0.90 kg and moves at constant speed on a cicle that is paallel to the gound. The path of the aiplane and the guideline lie in the same hoizontal plane because the weight of the plane is balanced by the lift geneated by its wings. Find the tension in the 17 m guideline fo a speed of 19 m/s. Januay, 017
15 Vetical Cicula Motion q In vetical cicula motion the gavitational foce must also be consideed. An example of vetical cicula motion is the vetical loop-the-loop motocycle stunt. Nomally, the motocycle speed will vay aound the loop. q The nomal foce, FN, and the weight of the cycle and ide, mg, ae shown at fou locations aound the loop. Januay, 017
