l I ) A curve has a radius of 20 meter and a banking angle ot'30 degrees. Assuming a static coefficient of friction 0,7 ofthe car's tires to the road, a) Draw the free body diagram of the car on the bank? b) What is the speed you can safely use for the cat to not slide up or down the embankment? e) What would happen ifthe car's speed was lower than your answer from part B'? d) What would happen ifthe car's speed was higher than your answer from part B? C) Assuming there is no friction. could the car still get around the eun-'e'? It so. what is the precise speed required? If not explain. 12) A400g particle is released from rest at point A on the inside of a smooth hemispherical bowl of. radius R410 cm. Calculate: at) its gravitational potential energy at A relative to B. h) its kinetic energy at B. e) its speed at B'.' d) its potential energy at C relative to B. e) its speed at C
