Four position -time graph are shown below.

a.

b.

c.

d.

a. a and c only

b. all the four

c. b and D only

d. b only

. The instantaneous velocity is given by the slope of the displacement time graph.

Since slope is positive in graph a and c.Positive velocity is there in a and c curve

Hence (a) and (c) are correct

a. a and b only

b. all the four

c. a and c only

d. c only

. The instantaneous velocity is given by the slope of the displacement time graph.

Since slope is negative in graph b and d.Negative velocity is there in b and d curve

Hence (b) and (d) are correct

a.

b.

c.

d.

.

The velocity will increase with time so b is the correct answer

Hence (b) is correct

a.

b.

c.

d.

. The equation for the given graph is

v=-(v

Differentiating both sides we get

dv/dx=-v

Now

a=v(dv/dx)

or

a=(-v

or

a=mx+c

where m=v

and c=-v

So that means slope is positive and intercept is negative

So (d) is correct

A stone is thrown vertically upwards with a initial speed of 10 m/s from the edge of the roof of the house of Height H=20 m

a) how long does it takes for the stone to hit the ground

b) At what velocity it will hit the ground

t=3.28 sec

v=-22.2 m/s

A body fell from rest from a height H above the ground. In the last 1 sec of the its fall, it travelled a distance H/2 . Find the value of H

H=57.1 m

If the body loses half of its velocity on penetrating 3 cm in the wooden block,then how much will it penetrate more before coming to rest?

1 cm
