The kinetic energy (in joules ) of a moving object can be calculated from the expression 1/2mv to the second power, where m is the mass of the object in kilograms and v is it’s speed in meters per second. find the kinetic energy of a 0.145-kg baseball that is thrown at a speed of 40 meters per second. e = joules

E = 1/2 m v^2

E = 1/2 (0.145) (40)^2

E = 0.0725 x 1600

E = 116 kg m^2/s^2

1 joule = 1 kg m^2/s^2

so here E in joules is 116 joules

so E = 116 joules

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
