$[$Multiple Choice$]$

A cannon is fired from a cliff of height $\backslash ($ y $\backslash )$ with a velocity $\backslash ($ v $\backslash )$ or $\backslash (25\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ The cannonball once fired begins it's trajectory at point $\backslash ($ A $\backslash )$ and hits the ground at point $\backslash ($ D $\backslash )$ Assuming air resistance can be ignored, complete the following statements.

$16.$ The $\backslash ($ y $\backslash )$ component of acce

component of acceleration at point A$.$

a$.$ greater than

b$.$ less than

c$.$ equal to

d$.$ unable to be compared to

e$.$ none of the above complete the statement correctly.

$17.$ The $\backslash ($ x $\backslash )$ component of velocity at point $\backslash ($ D $\backslash )$ is the $\backslash ($ x $\backslash )$ component of velocity at point $\backslash ($ A $\backslash ).$

a$.$ greater than

b$.$ less than

c$.$ equal to

d$.$ unable to be compared to

e$.$ none of the above complete the statement correctly.

$18.$ The $\backslash ($ y $\backslash )$ component of velocity at point $\backslash (\backslash$mathbf$\{$A$\}\backslash )$ is the $\backslash ($ x $\backslash )$ component of velocity at point $\backslash ($ C $\backslash ).$

a$.$ greater than

b$.$ less than

c$.$ equal to

d$.$ unable to be compared to

e$.$ none of the above complete the statement correctly.

$19.$ When a certain force is applied to an object with a mass of $2$ kg $,$ its acceleration is $\backslash (10\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}^\{2\}\backslash ).$ When the same force is applied to a different object, its acceleration is $\backslash (4\mathrm{.}0\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}^\{2\}\backslash ).$ What is the mass of the second object?

a$.1\mathrm{.}25$ kg

b$.2\mathrm{.}50$ kg

c$.5\mathrm{.}0$ kg

d$.10\mathrm{.}0$ kg

e$.$ There is not enough information to determine.

$20.$ A $10$ kg ball is suspended by two strings. Using the information given, compare the tension in each string.

a$.1\mathrm{.}25$ kg

b$.2\mathrm{.}50$ kg

c$.5\mathrm{.}0$ kg

d$.10\mathrm{.}0$ kg

e$.$ There is not enough information to determine.
