Kinetic energy can be calculated using the formula KE=1/2mv², where m= mass and v= velocity.
Calculate the kinetic energy of an object with mass 5kg moving at a velocity of 4m/s.

40J

Step-by-step explanation:

YOU say 1/2 x 5 x4² ( 4 is velocity. 5 is mass )

it becomes 1/2 x5 x16

then it becomes 1/2 x 80

half of 80 is 40

the answer is then 40 JUOLES

i’m sorry but i don’t know sorry

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
