Answer: A satellite with a mass of 110 kg and a kinetic energy of 3.08×10^9 J must be moving at a speed of 7483 m/s.
Explanation: To find the answer we need to know about the kinetic energy of a body.
<h3>How to solve the problem the equation of kinetic energy?</h3>- We have the expression for kinetic energy of a body as,
- Given that,
- We have to find the speed of the satellite,
Thus, we can conclude that, the velocity of the satellite will be 7438m/s.

Answer:
Impulse will be 12 kgm/sec
So option (b) will be correct option
Explanation:
We have given mass of the baseball m = 0.15 kg
Ball speed before hit
Ball speed after hitting ( negative direction due to opposite direction )
We have to find the impulse
We know that impulse is equal; to the change in momentum
So change in momentum =
So option (b) will be correct option
