One way to attack a satellite in earth orbit is to launch a swarm of pellets in the same orbit as the satellite but in the opposite direction.
suppose a satellite in a circular orbit 500 km above earth's surface collides with a pellet having mass 4.0g.

(a) what is the kinetic energy of the pellet in the reference frame of the satellite just before the collision?

(b)what is the ratio of this kinetic energy to the kinetic energy of a 4.0 g bullet from a modern army rifle with a muzzle speed of 950m/s? show all steps. for each equation write what and/or why you are using the equation.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

where is the photo and the answer choices?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
