The friction of the air causes a vertical retardation equal to `10%` of the acceleration due to gravity. Take `g=10 m//s^(2)` the maximum height and time to reach the maximum height will be decreased by

The friction of the air causes a vertical retardation equal to 10% of the acceleration due to gravity (take g=10ms^(-2)) The maximum height will be decreased by:

The friction of the air causes a vertical retardation equal to 10% of the acceleration due to gravity (take g=10ms^(-2)) The maximum height will be decreased by:

If the friction of air causes a vertical retardation equal to 10% of the acceleration due to gravity then the maximum height and time to reach the maximum height will be decreased by (g = 10ms^(-2))

If retardation produced by air resistances to projectile is one-tenth of acceleration due to gravity, the time to reach maximum height approximately-

If retardation produced by air resistances to projectile is one-tenth of acceleration due to gravity, the time to reach maximum height approximately-

A rocket is fired upwards such that its engine takes 10 s to explods fully. Its velocity- time graph is as shown in the figure. Acceleration due to gravity is 10m//s^(2) . The maximum height attained by the rocket is
