Suppose a fly orbits you (on the horizontal plane) with a constant orbital radius of 5 meters and subject to a time-varying (tangential) acceleration given by the expression a ( t ) =1+t with an initial speed of 2 m/s. Since the fly remains a constant distance away from you, you cannot use your flyswatter the way you would like to. Suppose that you can throw your flyswatter with an initial speed of 15 m/s in any direction you want. If you throw at t=0, how, exactly, should you throw your flyswatter to hit the fly? (Give both the angle above the horizontal to throw your flyswatter –and- at what angle ahead of the fly to throw it). ..
A golf ball is launched with the initial conditions shown in the figure. Determine the radius of curvature of the trajectory and the time rate of change of the speed of the ball (a) just after launch and (b) at apex. Neglect aerodynamic drag. (b) At the apex, determine the speed v of the ball, the total acceleration a of the ball, the normal component of acceleration an and the tangential component of acceleration at.Answers: v = ft/sec a = ft/sec2 an = ft/sec2 at = ft/sec2
