Applied Mechanics and Graphic Statics The velocity of a body fallen from height ‘h’, on reaching the ground is given by v = √(2gh) v = 1/√(2gh) v = 2gh v = 2gh² v = √(2gh) v = 1/√(2gh) v = 2gh v = 2gh² ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Newton’s Law of Motion is: The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts All listed here To every action, there is always an equal and opposite reaction Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts All listed here To every action, there is always an equal and opposite reaction Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force ANSWER DOWNLOAD EXAMIANS APP
