80 m 1979B1 From the top of a cliff 80 meters high a ball of mass 0 4 kilogram is launched horizontally with a fekty of 30 meters per second at time 1 0 as shown above The potential energy of the ball is zero at the bottom of the cliff Use g 10 meters per second squared a Calculate the potential kinetic and total energies of the ball at time t 0 b On the axes below sketch and label graphs of the potential kinetic and total energies of the call as functions of the distance fallen from the top of the cliff Energy joules 500 400 300 Energy joules 200 100 30 m s 200 0 100 0 Top of diff 20 30 Distance Fallen m 50 c On the axes below sketch and label the kinetic and potential energies of the ball as functions of time until the ball hits 600 500 60 5 70 6 Bottom of cliff 8
