Physics 1-6.

Task #1 - Module 2 INSTRUCTIONS: You must complete the following math problems. You must submit them in pdf format. If you do the problems by hand, it is important that they are legible. Remember, yes I don't understand what they write, I can't correct it. Always answer the problem questions. The work must include Cover and References (if any) They MUST teach the entire mathematical procedure to arrive at the result. Problems with results only will have zero points. 1.A child sitting 1.20 m from the center of a Ment-goround moves with a speed of 1.10 mis. Calculate (a) the child's centripetal acceleration and (b) the net horizontai force exerted on the child. Image of a Mary-Goround 2. An airplane traveling at constant speed begins to plummet m0ving in an arc radius of 5.20 km. What is the acceleration of the plane at G? 3. A horizontal force of 310 N is exerted on a 2.0 kg ball as it rotates (at arm length) uniformly in a horizontal circle of radius 090 m. Calculate the speed of the ball. 4. What is the magnitude of the acceieration of the base of a potter's wheel rotating at 45 rpm (revolutions per minute) if the diameter of the wheel is 35 cm? 5. A 0.55 kg ball, attached to the end of a horizontal cord, rotates in a circle of radius 1.3 rn on a frictionless horizontal surface. If the cable were to break when the tension on it exceeds Y5 N, what is the maximum speed that the ball can have? 6. How fast (in rpm) should a centrifuge spin if a particle 7.00 cm from the axis of rotation experiences an acceleration of 125,000 g
