\vec{A}

and

\vec{B}

\theta,

then the value of the product

(\vec{B} \times \vec{A}) \cdot \vec{A}

equals

Q2PhysicsUnit 2: Kinematics

A ball is thrown from the top of a tower with an initial velocityof

10 \mathrm{m} / \mathrm{s}

at an angle of

30^{\circ}

above the horizontal. It hits theground at a distance of

17.3 \mathrm{m}

from the base of the tower.The height of the tower

\left(\mathrm{g}=10 \mathrm{m} / \mathrm{s}^{2}\right)

will be

Q3PhysicsUnit 2: Kinematics

Q6PhysicsUnit 2: Kinematics

Q Type your question. moving horizontally with a speed

u

perpendicular to the direction of

v

enters through a hole at an upper corner

A

and strikes the diagonally opposite corner

B

. Assume

g=10 m / s^{2} .

Which of the following values of

u

and

is(are) correct? This question has multiple correct options

Q7PhysicsUnit 2: Kinematics

A particle projected from the origin

(x=y=0)

moves in

x y

plane so that its velocity is

v=(2 \hat{i}+4 x \hat{j}) \mathrm{m} / \mathrm{s},

when it is at point

(x, y)

(\hat{i} \text { and } \hat{j}

are the unit vectors along

x

and

y

axis). What is the value of

y,

when

x=3

Q8PhysicsUnit 2: Kinematics

Assertion In case of a projectile, the angle between velocity and acceleration changes from point to point. Reason Because its horizontal component of velocity remains constant, while vertical component of velocity changes from point to point due to gravitational acceleration.
