Q1. After the Sun exhausts its nuclear fuel, its ultimate fate might be to collapse to a white dwarf state. In this state, it would have about the same mass as it has now, but its radius would be equal to the radius of the Earth.
Compute the gravitational potential energy associated with a 4.51 kg object at the surface of the white dwarf.
Q2. A block rest on table top undergoing simple harmonic motion (a (tabletop) = -2 pi/T)^2 x, of amplitude A and period T with vertical oscillations.
Examine motion in acceleration frame of the tabletop at highest point table top motion. Give a detailed Forced Diagram.
Suppose a chimpanzee swings through the jungle on vines. If it swings from a tree on a 13 m long vine that starts at an angle of 45 degrees, what is the chimp's velocity when it reaches the ground.
A shuffleboard disk is accelerated to the speed of 6.1 m/s and released. If the coefficient of kinetic friction between disk and the concrete court is 0.30, how far does the disk go before it comes to a stop? The courts are 14.5m long.
A 0.180 kg baseball, travelling 32.0 m/s, strikes catcher's mitt that recoils 13.0 cm in bringing the ball to rest. What was an average force (in newtons) applied by the ball to the mitt.
What will be the equilibrium temperature while a 238 block of copper at 230 is placed in a 133 aluminium calorimeter cup containing 831 of water at 16.0.

How much farther from the tower does the cannonball from the higher cannon land than cannonball from the lower cannon.
Find the typical speed for a tsunami. (Note down that in the open ocean, tsunamis generally have amplitude of less than a meter, allowing them to pass ships unnoticed. As they approach shore, however, water depth decreases and the waves slow down. Th..
A block with mass m = 15kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4234N/m after being compressed the distance x1 = 0.536m from the spring's unstretched length. The floor is frictionless except for a roug..
