3(7x+5y=32) and -7(3x+4y=23)
To make 21x+15=96 and -21x-28y=-161
Then add them to be -13y=-65
So y=-5
The substitute y
3x-20=23
3x=3
So x=1

What is the kinetic energy of a 54 kg mass traveling at 15 meters per second?
kobusy [5.1K]

Given that an object with a mass of 54kg travels at 15m/s^2, determine the kinetic energy of the object.

KE =  0.5 x mv^2

M (mass) = 54kg

V (velocity) = 15m/s^2

Then, we plug the values in.

KE =  0.5 x 54(15^2)

Now, we solve.

KE = 0.5 x 54(225)

KE = 0.5 x 12150

KE = 6075

Now, that we have solved the formula, we can see that the kinetic energy of the object is 6,075J.

Thus, the kinetic energy of the object is 6,075J.
