A string of a material of length 1 in, cross-sectional area 0.2 cm2 requires 2000 N to extend it by 1 mm. The same material is used to manufacture the legs of a robot of 50 cm length and of cross-sectional area 0.5 cm2 each. The mass of the robot is 50kg. When it jumps from a building of height 'h' it experiences a strain 0.05. The maximum height through which the robot can jump without breaking its legs is (g = 10 ms−2)
