Question

Understanding how kinetic energy scales with mass and speed Decide how the objects in the following table would be listed, if they were listed in order of increasing kinetic energy. That is, select "1" next to the the lowest kinetic energy, select "2" next to the object with the second lowest kinetic energy, and so on. object A 6300. kg satellite moving at 7600. m/s. A 6300 kg satellite moving at 7870. m/s. kinetic energy (choose one) (choose one) (choose one) e (choose one) A 7330. kg satellite moving at 7870. m/s. A 6900. kg satellite moving at 7870. m/s.

Answer 1

use kinetic energy formula and relation between kinetic energy,mass of the object and velocity of the object.
Kinectic energy due to its energy possessed by an in the motion. object KE Kie - m= v Kinectic energy of the object mass of the object Velocity of the object a) A 6300 kg satellite moving at 7600 ms. m= 6300 kg = 7600 mls. KE 146300 x (7600) XG8004x 26 oy 7600 mg KE 1 X 6300kgy 57760 000 (m2 1 X 363888 X 10' 1 Joule = 1 kg J. Lonest kinecke b) KE = 181944 x 106 T. KEE 181944000000 J o energy A 6300kg satellite moving at 78.70 ms. m=6300 leg bv- 7870 m/s KE= I mv2 =) KE= £ X 6300 x 7870 X7870 KE = 1x6300 x 61936900 KE = 1.390202470000 KG = 195101235000 I

CA 7330 kg satellite moving at 7870 mis m = 7330kg = 7870 m/s KE-1 x 7330X 7870 x 7870 KE = I x 7330X 61936900 highest Kinetic X 453997477000 energy KE = d) = 20 G 9998 KE = 226998738500 J | + 6 A 6900 leg satellite moving at 7870 m/s. m=69ookg = 7870 ls. KE = I mu? - KE I X6900 X 7870 x 78.70 KE = I x 69000 61936900 = KE = _/x 4 27364610000 KE= 213 682 305 000 J To So the highest kinetic energy is of part ② and the lowest kinectic energy in of part ② hence increasing order KE 1 @ < ③ < @ < ① l From above data we get to know that the object having high more mass and more velocity will have higher Kinectic energy If two objects are moving with same velocity then the dese object with more mass (on the heavier object) will have more kinectic chergy. If two objects are having same mass than the objed moving faster (on the object having more velocity) will have higher (more) Kinectic energy.
