A body is freely dropped from a height h above the ground. Find the ratio of distances fallen in first one second, first two seconds, first three second first two seconds, first three seconds, also find the rato of distances fallen in `1^(st)` second, in `2^(nd)` second, in `3^(rd)`

From second equation of motion i.e. `h=(1)/(2)"gt"^(2)(h=ut+(1)/(2)"gt"^(2)` and u=0)
`h_(1):h_(2):h_(3)......=(1)/(2)g(1)^(2):(1)/(2)g(2)^(2):(1)/(2)g(3)^(2)=1^(2):2^(2):3^(2)......=1:4:9....`
Now from the of distance travelled in `n^(th)` second `S_(n)=u+(1)/(2)a(2n01)` here u=0, a=g
`S_(n)=(1)/(2)g(2n-1)` or `S_(1):S_(2):S_(3):......=(1)/(2)g(2xx1-1):(1)/(2)g(2xx2-1):(1)/(2)g(2xx3-1)=1:3:5.....`

A body is dropped from rest from a height h. It covers a distance `(9h)/(25)` in the last seconds of fall. The height h is : (use `g = 9.8 m//sec^(2)`

Correct Answer - C t is the time to reach ground. `h= (1)/(2) at^(2) , (1 - (9)/(25)) h = (1)/(2) a (t - 1)^(2)` `(1 - (9)/(25)) = ((t -...

A force given by the relation F = 8t, acts on a body of mass 2 kg, initially at rest. Find the work done by this force on the body during first 2 seco

Correct Answer - A `F = 8t` `m (dv)/(dt) = 8t` `m underset(0)overset(v)int dv = 8 underset(0)overset(t)int t dt` `mv 4t^(2)` or `m = (dx)/(dt) = 4 t^(2)` `rArr dx =...

A body of mass `1 kg` suspended an ideal spring oscillates up and down. The amplitude of oscillation is `1` metre and the periodic time is `1.57` seco

Correct Answer - A::D (i) Maximum speed of oscillating body `v_(max) = Aomega = A xx (2pi)/(T)` Here `A = 1` metre, `T = 1.57 s` `v_(max) = (2 xx 3.14...

A body of mass 20kg is initially at a height of 3m above the ground. It is lifted to a height of 2m from that position.

Mass, m = 20kg Height m, H = 3m Potential Energy, (PE1) = mgH PE1 = 20 x 9.8 x 3 PE1 = 588 joules Now Height (h) is 5m (3m + 2m) (PE2) = mgh (PE2)...

Two balls are dropped from different heights at different instants. Seconds ball is dropped 2 sec. after the first ball. If both balls reach the groun

Correct Answer - B `h_(1)-h_(2)=(1)/(2)g(t_(1)^(2)-t_(2)^(2))=(1)/(2)xx9.8(5)^(2)-(3)^(2)` `=8xx9.5=78.4m`

A small sphere of mass m is dropped from a height After it has fallen 100 m it has attained its terminal velocity and continues to fall at that speed.

Correct Answer - B In the first `100m` body starts from rest and its velocity goes on increasing and after `100m` it acquire maximum velocity (terminal velocity). Further, air friction i.e...

Two balls of same mass are dropped from the same height h, on to the floor. The first ball bounces to a height h/4, after the collision `&` the second

`(I_(2))/(I_(2))=(msqrt(2gh)+msqrt(2gh//4))/(msqrt(2gh)+msqrt(2gh//16))` `=(1(1)/(2))/(1+(1)/(4))=((3)/(2))/((3)/(4))=(6)/(5)`
