On Oct 31 2015, massive asteroid TB145 nicknamed "Spooky" passed near the Earth
vicinity. The measured diameter of the asteroid: 600meters, and its speed relative to
the Sun: 30.5 km/s.
(NOTE you are not given the parameters of collision, so they become important part
of the "worst case -best case scenario.") Treat the asteroid as spherical object with
the density of between 3g/cm³ to 4g/cm³. Treat an Earth's orbit around the Sun as a
perfect circle of radius =150 x 106 km. Take one year to be 365.24days.
Find the worst case scenario for the collision of such object with the Earth and find
the Maximum energy released in the completely inelastic collision of this object with
Earth. State your answers to the nearest mega-ton of TNT. (1 megaton of TNT=
4.184 X1015J).

Consider a large but thin sheet of plastic with a uniform −3.3 × 10-6 C/m2that is being held parallel to the xz-plane and passing through the origin. At some time a small glass bead with 0.14 kg and 6.5 × 10-6 C is released from rest at 0.9 m on the y-axis. What will be the acceleration of the bead immediately after being released?
Two stars each of one solar mass (= 2×1030 kg) are approaching each other for a head on collision. When they are a distance 109 km, their speeds are negligible. What is the speed with which they collide ? The radius of each star is 104 km. Assume the stars to remain undistorted until they collide. (Use the known value of G)

- For years, the tallest tower in the United States was the Phoenix Shot Tower in Baltimore, Maryland. The shot tower was used from 1828 to1892 to make lead shot for pistols and rifles and molded shot for cannons and other instruments of warfare. Molten lead was dropped from the top of the 82.15 m tall tower into a vat of water. During its free fall, the lead would form a perfectly spherical droplet and solidify. Determine the velocity of the droplet right before it hits the ground. (Note: acceleration = -9.81 m/s/s) (Hint: think about the direction the droplet travels when considering its displacement.) ___________m/sarrow_forwardA 12 kg space rock with velocity vector v1 = 7 i (m/s) collides with and sticks to an 22 kg space rock with velocity vector v2 = 21 j (m/s).

This initial orbit is shown in the upper left drawing. At the position marked by x in the drawing the satellite's rocket motor is fired briefly (assume instantaneously), giving the satellite an impulse in the direction of its motion (i.e. tangentially). This impulse changes the velocity of the satellite to Avg. The impulse is such that the farthest point from the earth that the satellite will reach is 2ro. : Find the initial velocity of the circular orbit. Use m for the satellite (a) mass, M for the earth's mass, G for the gravitational constant, and vo for the velocity. (b) of the satellite? Explain your answer, perhaps by saying what is wrong with all the incorrect drawings.
