An object moving with a speed of 67 m/s and has a kinetic energy of 500 j, what is the mass of the object.

mass of object is 0.22kg

Explanation:

Given:

speed of object = 67m/s

kinetic energy of object = 500J

Mass of object: ?

Using the kinetic formula,

E = mv²/2

where

E = kinetic energy of object

v = speed of object

m = mass of object

substituting into the formula, we have

500 = (m * 67²)/2

Cross multiplying, we have

500 * 2 = 67² * m

simplifying, we have

1000 = 4489m

making m subject formula, we have

m = 1000/4489

m = 0.22kg

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
