Q3) Assuming the Earth's orbit is circular with radius R, the distance it travels in one year would be the circumference = 2\pi R. Calculate the Earth's orbital speed (in km/s) using that along with the numbers in the previous paragraph. Q4) Any force that bends the path of an object along a circular arc is called a "centripetal force", for the Earth's orbit it is the gravitational pull of the Sun that provides the centripetal force. If a centripetal force is causing a mass m to move along a circular arc of radius R at a speed v, the exact strength of that force must be equal to $mv^2/R$. For the Earth's orbit, that means: $GMm/R^2 = mv^2/R$ Use this formula to solve for the Earth's speed v. Then put in values, M is the Sun's mass, m is the Earth's mass (but note it cancels out in the equation), and R is the Earth-Sun distance. You should convert R into meters before substituting it into the equation, you'll get v in m/s, finish the problem by converting that to km/s. Show all your work, you should get the same answer as you got for Q3.
