Part A A slingshot obeying Hooke's law is used to launch pebbles vertically Assuming that air drag is negligible, how high will the pebble go if you pull it back 30.4 cm instead? into the air. You observe that if you pull a pebble back 15.2 cm against the elastic band, the pebble goes 4.9 m high. Express your answer with the appropriate units. HA h = Value Units Submit Request Answer Part B How far must you pull it back so it will reach 9.8 m? Express your answer with the appropriate units. HA Value Units Submit Request Answer Part C If you pull a pebble that is twice as heavy back 15.2 cm, how high will it go? Express your answer with the appropriate units. HA h = Value Units
