The speed of light is 2.99 x 10 8 meters/second. If the sun is 1.5 x 1011 meters from earth, how many seconds does it take light to reach the earth?

A speed of 70 m/s is the greatest speed that a meteorite can have and still he pulled down to earth surface. If a meotoride traveling with this speed has a kinetic energy of 25,600 j what’s its mass

He is incorrect: Because you can multiply unlike term like X and Y and you will get=XY, But you cannot add unlike term like 2X+3Y=_____.
