The equation K = mv2 represents the energy an object has based on its motion. The kinetic energy, K, is based on the mass of the

object, m, and the velocity of the object, v. Lashandra is given K and v for 10 different objects. In order to make solving more efficient, she solves the equation for m : m = . After attempting to determine the mass of a few objects, Lashandra realizes there must be something wrong with her formula. What is Lashandra’s error?

Kinetic energy<span> is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has </span>kinetic energy<span>. It is expressed as:

KE = mv^2 / 2

Therefore, her error would be that he lack the factor 1/2 in her formula. Hope this answers the question. Have a nice day.</span>

What is the result when 55 increased by 209%?
Tju [1.3M]
55 increased by 209%

Since we are increasing by 209% ,

New value would be = 100% + 209% = 309%  of the old value which is 55.

 =   309%  * 55

=  (309/100)  * 55

=  3.09 * 55 = 169.95

The result is 169.95

Find the area of this shape.
skad [1K]

Answer:

Step-by-step explanation:

Firat triangle has a=4cm and b=a and P1=a*b/2=4*4/2=8cm^2

First parallelogram has h=4cm (from first triangle) and a=5.7cm

P2=a*h=22.8cm^2

Big triangle has h=4 and a=5.7+4=9.7

P3=a*h/2=9.7*4/2=19.4

And 4th triangle has the same are lik the first one, P4=8.

P=8+22.8+19.4+8=58.2cm^2
