4. A rock of mass 4.0 x 102 g is tied to one end of a string that is 2.0 m in length. Holding the other end above his head, a boy swings the rock around in a circle whose plane is parallel to the ground. Draw a free body diagram andſexplain your steps in detail, neatly. a. If the string can withstand a maximum tension of 4.5 N before breaking, what angle to the vertical does the string reach just before breaking? b. At what speed is the rock travelling just as the string breaks?

A. Given that a racecar with a mass of 795.0 kg is going through an unbanked curve of a constant radius of 122.0 meters, with racing tires with a static friction coefficient of 0.85 with the race track, what is the maximum speed that the racecar can take with the curve and not slide, assuming the car generates no negative lift? B. How much frictional force does the car need to generate to follow the curve without losing control or slipping? C. Would the speed of the racecar change if the experiment was conducted on an alien planet with a gravity of 8 m/s^2?

1. A racing bicycle with rider has a combined mass of 85 kg. The racer is on a velodrome (circular racing track) that has banked curves. The surface is banked at an angle of 35° from horizontal. The track has a radius of 60 m. a) Draw a free-body diagram of the racer viewing the racecar from the front (left) and from above (right.) Ignore friction. Indicate the direction of the acceleration of the racer next to your diagram. b) Based on your free-body diagram do you think the car could possibly stay on a circular path (the track) without friction? Explain. c) Which of the forces you drew has a component in the same direction as the acceleration? Explain. d) Write down your force equations and solve for the acceleration of the racer moving at a constant speed around the track with no friction. (Hint: Use the direction of the acceleration as one of your axes. Do not use along-the-incline and perpendicular-to- the-incline as your axes.) e) What speed would the racer have with this…
