  • $\frac{3}{2}\,m / s \uparrow$
  • B
    $\frac{3}{2}\,m / s \downarrow$
  • C
    $\frac{1}{2}\,m / s \uparrow$
  • D
    $\frac{1}{2}\,m / s \downarrow$

Answer

Correct option: A.
$\frac{3}{2}\,m / s \uparrow$
a
From constrained

$+2-v_B-v_B+1=0$

$v_B=\frac{3}{2}\,m / s \uparrow$

A ring and a disc are initially at rest, side by side, at the top of an inclined plane which makes an angle $60^{\circ}$ with the horizontal. They start to roll without slipping at the same instant of time along the shortest path. If the time difference between their reaching the ground is $(2-\sqrt{3}) / \sqrt{10} \mathrm{~s}$, then the height of the top of the inclined plane, in metres, is. . . . . . Take $g=10 \mathrm{~m} \mathrm{~s}^{-2}$.
A ball is released from certain height. It loses $50\%$ of its kinetic energy on striking the ground. It will attain a height again equal to
A particle moving in a circle of radius $R$ with uniform speed takes time $\mathrm{T}$ to complete one revolution. If this particle is projected with the same speed at an angle $\theta$ to the horizontal, the maximum height attained by it is equal to $4 R$. The angle of projection $\theta$ is then given by :
