The kinetic energy is calculated through the equation,
KE = mc²
where KE is kinetic energy, m is mass, and c is the masses. Substituting the known values,
KE = (5 kg)(3 x 10^8)²
KE = 4.5 x 10^17 J

Answer:
x = 12.25
Step-by-step explanation:
x : 14 = 7 : 8
x/14 = 7 /8
x = (7 * 14 ) / 8
= (7 * 7) / 4
=49 /4
= 12.25
x = 12.25
Answer:
Step-by-step explanation:
L=3W
P=2L+2W
56=2*3W+2W
56=6W+2W
8W=56
W=56/8
W=7 ANSWER
FOR THE WIDTH.
L=3*7=21 ANS.
FOR THE LENGTH.
PROOF:
56=2*21+2*7
56=42+14
56=56
