Solve Using Work/Energy Methods :On an asteroid like Bennu, where NASA just landed a probe on October 20, a pressurized nitrogen canister is used to break rocks loose from the surface. One of those rocks is launched straight upward from the surface.(HCPCRN32387)If the initial speed of the rock is 520 m/s,determine the maximum height it reaches if the mass of the asteroid is only 5% that of the earth’s while the radius is 12% that of the earth’s

- Find the speed needed to escape from the solar system starting from the surface of Earth. Assume there are no other bodies involved and do not account for the fact that Earth is moving in its orbit. [Hint: Equation 13.6 does not apply. Use Equation 13.5 and include the potential energy of both Earth and the Sun. Substituting the values for Earth’s mass and radius directly into Equation 13.6, we obtain vesc=2GMR=2(6.67 10 11Nm2/kg2)(5.96 10 24kg)(6.37 106m)=1.12104m/s That is about 11 km/s or 25,000 mph. To escape the Sun, starting from Earth’s orbit, we use R=RES=1.501011m and MSum=1.991030kg . The result is vesc=4.21104m/s or about 42 km/s.

(a) Yes, and at the surface it would be larger in magnitude than 9.8 N/kg. (b) Yes, and it would be essentially the same as the current value. (c) Yes, and it would be somewhat less than 9.8 N/kg. (d) Yes, and it would be much less than 9.8 N/kg. (e) No, it would not.arrow_forwardReview. As an astronaut, you observe a small planet to be spherical.
