Solution

The correct option is B fly side by side with the parent stone along parabolic path
The piece will fly side by side along a parabolic path, since the horizontal velocity will not change and remains the same from initial to final point. The vertical component of velocity, at the instant it separates from the stone is same as that of the stone's vertical component.
Hence, the piece will fly side by side.

A piece of stone is thrown vertically upwards. It reaches the maximum height in 3 seconds. If the acceleration of the stone be $9.8 m / s^{2}$ directed towards the ground, calculate the initial velocity of the stone with which it is thrown upwards.

Q. Two stones are projected simultaniously from a tower at different angles of projection with same speed

u

. The distance between two stones is increasing at constant rate

u

. Then the angle between the initial velocity vectors of the two stone is:

Q. A stone is projected with a velocity

20 \sqrt{2} m / s

at an angle of

45^{o}

to the horizontal. The average velocity of stone during its motion from starting point to its maximum height is:

(g = 10 m / s^{2})

Q. A stone is projected horizontally with speed

10 m / s

from a height

h

above the ground. A horizontal wind is blowing in the direction opposite to the velocity of projection and gives the stone a constant horizontal acceleration

10 m / s^{2}

(in the direction opposite to the initial velocity). As a result the stone falls on ground at a point vertically below the point of projection. Then the value of height

h

is (

g = 10 m / s^{2}

)
