Centripetal Acceleration: A car moving with a constant speed of 80 km/h enters a circular, flat curve with a radius of curvature of 0.50 km.  If the friction between the road and the car’s tires can support a centripetal acceleration of 1.20 m/s2, without slipping, does the car navigate the curve safely, or does it fly off the road? Perform calculations to justify your answer. Be sure to perform all the necessary dimensional conversions to mks units.

A soccer ball of mass 0.4 kg is moving horizontally with a speed of 20 m/s when it is kicked by a player. The kicking force is so large that the ball flies up at an angle of 30 degrees above the ground. The player however claims (s)he aimed her/his foot at a 40 degree angle above the ground. First briefly but precisely explain how this is possible, based on what you heard in the lecture. Then calculate the average...
