5. All the ramps are 5 m high. We know that the KlB of the block at the bottom of the ramp will be equalso the loes of PB (conservation of energy). Pind the speed of the block at ground level in each acast THint: Do you recall from esrlier shapters how long it takes something to Ball a verical distance of 5 m from a positon of rest (aseume g 10 m/st And how much speed a falling object acquires in this time? This gives you the answer to Case 1. Discuss with your classmates how energy conservation gives you the answers to Cases 2 and 3.1 5m Case 1:Speed m/s Case 2: Speed= Case 3: Speed= m/s m/s %3D
