A centripetal force of 190 N acts on a 1,550-kg satellite moving with a speed of 5,300 m/s in a circular orbit around a planet. What is the radius of its orbit?

Radius, r is equal to 229.16×10^6m

Explanation:

Given the following parameters;

Centripetal force on the satellite, Fc = 190N.

Mass of the satellite, M = 1,550-kg.

Speed of the satellite, V = 5,300m/s.

The relationship between a satellite of mass (m) moving in a circular orbit of radius (r) with a speed (v) and a centripetal force (Fc) is given by the equation;

Fc = (MV²)/r

Since, we're solving radius, r; we make "r" the subject of formula;

Thus, r = (MV²)/Fc

Substituting into the above equation;

r = (1550 × [5300]²)/190

r = (1550 × 28090000)/190

r = 43539500000/190

r = 229155263.16

Radius, r is equal to 229.16 × 10^6m

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

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.
