An object is falling freely under the gravitational force. Its velocity after travelling a distance h is v. If v depends upon gravitational acceleration g and distance,prove with dimensional analysis that v=k_/gh where k is a constant |

Answer» v = K√ghExplanation:An object is FALLING freely under the gravitational force. Its VELOCITY after traveling a DISTANCE h is v. object is falling freely => initial velocity = 0 velocity after traveling a distance h is v=> S = hV = va = g USING V² - U² = 2aS=> v² - 0 = 2gh=> v = √2gh=> v = √2√gh=> v = k√gh where k = √2 Constant |
