The earth orbits the sun once a year (3.16 107 seconds) in a nearly circular orbit of radius 1.5-10¹¹m. a) Assuming the earth travels at a constant speed, determine that speed. (Hint: Average speed distance / time. Distance around a circle is called the circumference of the circle.) VEarth = m/s b) Determine the size of the centripetal acceleration of the earth. m ac = c) Determine the size of the net centripetal force needed to keep the earth orbiting the sun. What is its direction? Fret N

Pls help ASAP

Which of these has not been suggested as a method to possibly deflect an asteroid from hitting Earth? O Using its own gravity to "tow" it. O Hitting it with explosions or impacts to push it. O Painting it. O Using rockets to push it. O All of these are possible methods to deflect an asteroid.
