Brendan drew a diagram to illustrate the centripetal force acting on a satellite. how can brendan correct his diagram? a. draw the fg = fc vector so it points at a 45° angle from the v vector. b. change the fg = fc vector label so it reads fa = fc. c. draw the fg = fc vector so it is longer than the v vector. d. change the fg = fc vector so it is perpendicular to the v vector.

Brendan drew a diagram to illustrate the centripetal force acting on a satellite.  

How can Brendan correct his diagram?

Draw the Fg = Fc vector so it points at a 45° angle from the v vector.  

Change the Fg = Fc vector label so it reads Fa = Fc.

Draw the Fg = Fc vector so it is longer than the v vector.  

Change the Fg = Fc vector so it is perpendicular to the v vector.

D is the answer

Change the Fg = Fc vector so it is perpendicular to the v vector.

Explanation:

Brendan drew a diagram to illustrate the centripetal force acting on a satellite.   When satellite rotates around a earth, the centripetal force is balanced by gravitational force such that,

Centripetal force is a type of force which is responsible for the motion of an object in a circular path. It is a center seeking force. If the centripetal force is absent, the satellite would move in a straight line. It is perpendicular to the velocity of satellite.

Hence, the correct option is (d) "Change the Fg = Fc vector so it is perpendicular to the v vector".

resonant frequency

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
