Mathematics: In physics, kinetic energy is the energy of an object in motion. Kinetic energy, K, measured in joules (J), is calculated using the formula K= 1/2mv^2, where m is mass of the object, measured in kilograms (Kg), and v is the velocity of the object, measured in meters per second (m/s). Rearrange the formula to solve for mass (M).

$m = \frac{2k}{v^{2} }$

Step-by-step explanation:

$k = \frac{1}{2} mv ^{2}$

$v ^{2} m = 2k$

$m = \frac{2k}{v ^{2} }$

31.7 cm^2

Solution,

In ∆ ABC

< A + <B + < C = 180°

or, 72 + 59 + <C = 180°

or, 131 + <C = 180°

or, <C = 180 - 131

< C = 49

Area of ∆ABC = 1/2 ab sin C

= 1/2 * 12 * 7 * sin 49

= 42 * sin 49

= 31.7 ( approximately)

Hope this helps...

Good luck on your assignment...
