Gravitational acceleration close to the surface of the earth is g=10 m/s. 1- A boy is standing distance d=5 m away from edge of a hill as shown in the figure. The height of the hill is H=1 m. The boy kicks a ball towards the hill with initial speed v-500 m/s and with angle A=45 degrees from horizon. a) What is the time it takes for the ball to reach the maximum height it reaches? b) At what distance from the edge of the hill will the ball land on the hill? c) What is the magnitude of the speed of the ball when it lands on the hill?
