three different object of massesm¹,m² and m³ are allowed to fall from rest and from the same point'o' along three different frictionless patgs. the speeds of the three objects, on reaching the ground, will be in the ratio of​

Answer 1

Explanation:

Three different object of masses m 1 ,m 2 ,m 3 are allowed to fall from rest from the same point along three different frictionless path, the speed of the three object on reaching the ground will be in ratio of?If the balls falls through the same height, whatever be the frictionless path, their velocity on reaching the ground will be equal. This is according to the law of conservation of energy.If they fall from a point at a height ‘h’ from the ground, the potential energy at the point is, PE = mghThe kinetic energy on reaching the ground is, KE = ½ mv 2Since, PE = KE=> mgh = ½ mv 2=> v = √(2gh)The equation is independent of mass
