Statement I: The tendency to overturn of skidding/overturning is quadrupled, when a cyclist doubles his speed of turning.

Statement II:

\tan \theta=\frac{\mathrm{v}^2}{\mathrm{Rg}} \Rightarrow

becomes 4 times as

v

doubled.

View answer and explanation

Correct option: A

If both Statement - I and Statement - II are true, and Statement - II is the correct explanation of Statement - I

Statement I and Statement II are both true, and Statement II correctly explains Statement I. The tendency to overturn increases with the square of the velocity, as shown by the equation

\tan \theta = \frac{{v^2}}{{Rg}}

A ball throwing cannon, lifts ball and throws with

72 \mathrm{~km} / \mathrm{hr}

Speed. If balls are raised upto

10 \mathrm{~m}

. then find Input power of cannon if it lifts 8 balls per minute and its efficiency is

80 \%

. Mass of each ball is

1 \mathrm{~kg}

. Assertion:When a particle moves in a circle with a uniform speed its acceleration is constant but the velocity changes.
Reason: Angular displacement is not an axial vector. A body of mass

m

thrown vertically upwards attains a maximum height

h

. As what height will its kinetic energy be

75 \%

of its initial value? Assertion: Centripetal force does no work.

Reason: Force and displacement are perpendicular to each other. Statement I: Both stretched and compressed springs possess potential energy.

Statement II: Work done against restoring force is stored as potential energy. A bullet of mass

m

moving at a speed

v

hits a ball of mass

M

kept at rest. A small part having mass

m^{\prime}

breaks from the ball and sticks to the bullet. The remaining ball is found to move at a speed

v_1

in the direction of the bullet. Find the velocity of the bullet after the collision.
