A m = 3.05 kg object hangs in equilibrium at the end of a rope (taken as massless) while a wind pushes the object with a Fw = 20.3 N horizontal force. Find the magnitude of the tension in the rope and the rope's angle from the vertical. The acceleration due to gravity is g = 9.81 m/s². 34.14 tension: N angle: Incorrect 36.16 Incorrect Wind
A trainer times his racehorse as it completes a workout on a long, straight track. The trainer's graph of his horse's position versus time is shown in the figure. Use the graph to calculate the average speed Uavg.1 of the horse between 0 and 15 s. Use the graph to calculate the average speed Uavg,2 of the horse between 15 s and 35 s. Use the graph to calculate the average speed Uavg.3 of the horse between 0 and 50 s.
