NEET 2013 | Motion in a Straight Line Question 18 | Physics

A stone falls freely under gravity. It covers distances h₁, h₂ and h₃ in the first 5 seconds, the next 5 seconds and the next 5 seconds respectively. The relation between h₁, h₂ and h₃ is

h₂ = 3h₁ and h₃ = 3h₂

h₁ = h₂ = h₃

h₁ = 2h₂ = 3h₃

$${h_1}$$ = $${{{h_2}} \over 3}$$ = $${{{h_3}} \over 5}$$

A particle covers half of its total distance with speed v₁ and the rest half distance with speed v₂. Its average speed during the complete journey is

$${{{v_1} + {v_2}} \over 2}$$

$${{{v_1}{v_2}} \over {{v_1} + {v_2}}}$$

$${{2{v_1}{v_2}} \over {{v_1} + {v_2}}}$$

$${{v_1^2v_2^2} \over {v_1^2 + v_2^2}}$$
