Situation $3$: A block weighing $100kN$ is pushed horizontally by a horizontal force of $100kN$ along the horizontal plane

from $A$ to $B,10m$ long. The velocity of the block at A is $10\frac{m}{s}.$ The block is released at B and passes through an upward

circular arc BC $($tangent to $B)$ of radius $10m$ and central angle of $45,$ and along an inclined plane $CD$ tangent to the arc at $C$

$*$Which of the following most nearly gives the velocity of block at B$?$

a$.$

$25\frac{m}{s}$

$b.$

$23\frac{m}{s}$

$c.$

$20\frac{m}{s}$

$d.$

$17\frac{m}{s}$

Which of the following most nearly gives the velocity of the block at C$?$

a$.$

$13\mathrm{.}5\frac{m}{s}$

$b.$

$11\mathrm{.}5\frac{m}{s}$

$c.$

$15\mathrm{.}5\frac{m}{s}$

$d.$

$10\mathrm{.}5\frac{m}{s}$

$*$Which of the following most nearly gives the distance along CD that the blocks will move before it comes to rest?

a$.17m$

$b.20m$

$c.14m$

$d.12m$
