A particle is thrown vertically upwards. If its velocity at half of the maximum height is 10 m/s, then maximum height attained by it is (Take g = 10 m/s²)

Three different objects of masses m₁, m₂ and m₃ are allowed to fall from rest and from the same point \'O\' along three different frictionless paths. The speeds of the three objects. on reaching the ground, will be in theratio of

From the top of a tower, a particle is thrown vertically downwards with a velocity of 10 m/s. The ratio of the distances, covered by it in the 3rd and 2nd seconds of the motion is (Take g = 10 m/s²)
