Two bodies A and B are thrown simultaneously with the same speed. The mass of A is greater than the mass of B suppose the air exerts a constant and equal force of resistance on two bodies. then how will A go higher than B? How is here mass related to height?

Success is how high you bounce when you hit bottom. |

YEAH.................
the force of resistance is the same............
since mass of B is lower..............
and force can be taken const, for A and B.........
acceleration of B will be higher than of A...........
So,
A will go more high.......................
'ope you got it..................
and pls rate me........................thanks ...........

yaar as air resistance is equal and speed is same so i think both will go upto the same height coz force of gravitation is independent of mass

Being beaten is often a temporary condition, giving up is what makes it permanent. |

Effective acceleration of the bodies
aA = g+R/mA
aB = g+R/mB
Height attained by the bodies
HA = u2 /2aA
HB = u2 /2aB
Let mA >mB
g+R/mA < g+R/mB
u2 /2aA > u2 /2aB
HA >HB
Hence the heavier mass attains greater height.

yaar..........
i am sure i am right.....................
viscous force acting on the bodies will be same........bt diff. acc........

Sorry for that redundant term "effective acceleration". It should be acceleration.
Got a bit carried away
And thanx krishna

speed is same
force is constant
mass of a is higher
acceleration of a is less
a will be higher
