Beings on spherical asteroid have observed that a large rock is approaching their asteroid in a collision course. at 7514 km from the center of the asteroid, the rock has a speed of 136.0 m/s and later at 2823 km it speed has a of 392.0 m/s. use energy conservation to find the mass of asteroid it. you can neglect any effects due to the parent star of the asteroid. (g = 6.67 times 10^-11 n. m^2/kg^2)

a. 6.112 times 10^28 kg
b. 4.582 times 10^20 kg
c. 4.582 times 10^21 kg
d. 9.164 times 10^27 kg.

c.

Explanation:

= Initial distance between asteroid and rock = 7514 km = 7514000 m

= Final distance between asteroid and rock = 2823 km = 2823000 m

= Initial speed of rock = 136 ms⁻¹

= Final speed of rock = 392 ms⁻¹

= mass of the rock

= mass of the asteroid

Using conservation of energy

Initial Kinetic energy of rock + Initial gravitational potential energy = Final Kinetic energy of rock + Final gravitational potential energy

he kicked it 10 feet straight up into the air? i think this works.

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.
