He must hold his umbrella at 40 degrees with the vertical to keep the rain away, He sees a bear at a distance. The man drops his umbrella and starts to run at 10 m/s, He notices that the rain drops new hit his head vertically. a) Draw a schematic of the situation. b) Write an expression relating the velocity vectors ofthe rain drops, running man and the relative velocity of the rain drops with respect to the running man. c) Calculate the velocity of the rain with respect to the ground, 29] A block of mass M rests on a fixed inclined plane. It is pulled With a rope attached to it With force F at an angle of 45 degrees to the horizontal. Assume all surfaces to be frictionless. ai Draw a free body diagram of the mass M. b) If M 10 kg, llnd F such that the block stays stationary on the Inclined plane. c) What is the force exerted by the block on the inclined plane iii that scenario? 30] A curve has a radius of R and a banking,r angle of 0, Assuming a static coefcient of friction pt of the car's tires to the road, what is the speed you can safely use for lebankmvm
