1. A 900-kg car moving at 10 m/s takes a turn around a circle with a radius of 25.0 m. Determine the acceleration and the net force acting upon the car. Known Information: m= 900 kg v = 10.0 m/s R = 25.0 m Unknown Information: a = ???? Fnet = ???? = a=v/R a (10.0 m/s)2/(25.0 m) a (100 m2/s2)/(25.0 m) a = 4 m/s2 Fnet ma Fnet (900 kg) (4 m/s2) Fnet = 3600 N 2. The maximum lift provided by a 500 kg airplane is 10000 N. If the plane travels at 100 m/s, what is its shortest possible turning radius? 3. A carousel rotates evenly, making a full rotation every 4.0 seconds. Each horse performs a uniform circular motion with a frequency in rps (rotation per second) equal to:
