Calculate the centripetal force on a 5.5 kg sensor that is attached at the end ofa 90.0m long Wind turbine blade that is rotating at 1.75 rev/s. kN a) A 22.0 kg child is riding a playground merrygOround that is rotating at 35.0 rpm. What force must she exert to stay on if she is 1.20 m from its center? N b) What centripetal force does she need to stay on an amusement park merrygOround that rotates at 3.00 rpm ifshe is 6.50 m from its center? N a) What is the mass of a large ship that has a momentum of 1.75 x 10' kg . m/s when the ship is moving at a speed of 45 km/h? x10 kg b) Compare the ship's momentum to the momentum of a 1040 kg artillery shell fired at a speed of 1205 m/s.a) At what speed would a 2.55 x 10*kg airplane have to fly to have a momentum of 1.75 x 10' kg? m/s b) What is the plane's momentum when it is taking off at a speed of 66.0 m/s? kg . m/s
