Charlie kicks a soccer ball up a small incline. On the way up,ball’s acceleration has magnitude |a| = 0.45 m/s2 and is directedin downhill direction. Charlie kicks the ball at the bottom of theincline and then immediately start to walk up the incline withconstant speed. Charlie performs twi different trials. a) In thefirst trial, Charlie kicks the ball with initial speed v0 = 3.4m/s. Charlie is 2.3-m behind the ball when the ball is at thehighest point. What is the speed vC of Charlie? b) Charlie performsthe second trial. He kicks the ball with unknown speed v 0 0 butwalks with the same speed vC as in the first trial. Charlie is now0.8 m behind the ball when the ball is at the highest point. Whatis the initial speed v 0 0 of the ball at the bottom of the hill?(Hint: You need to set-up a quadratic equation for v 0 0 ).
