Q. A 4.0 kg block is released from rest at the top of a 30 degree frictionless incline. The block makes a head on elastic collision with another 3.0 kg block initially at rest on a horizontal surface at the bottom of the incline. (A) if the coefficient of friction between the horizontal surface and the second block is 0.30, how far will the second block go on the ground? (B) If after the collision of the first block goes back up the incline, how high will it rise along the incline?

A double cylindrical drum system of radii 10 cm and 20 cm with masses 15 kg and 25 kg respectively, as shown has two weights of 250 N (smaller drum) and 120 N (larger drum) suspended by weightless cords wrapped around the drums. (A) Compute the amount of inertia of the system. (B) Analyse the magnitude and direction of angular acceleration.

A spherical planet consists of a dense core (density P1=6g/cm^3) of radius 4*10^3 km and a less dense outer sheath (density P2=3.50g/cm^3) of utter radius 12*10^3 km. (A) Calculate the moment of inertia of the planet about an axis throughout its center. (B) if the planet revolves units own axis once in 36h, what is its angular momentum?

The mass per unit of a 80 kg, 0.20 m radius , non uniform disk varies with distance from the center as p(r)=p0r. (A) What is the value of p0? Calculate the moment of inertia of the disk about an axis through its center and perpendicular its plane.

The angular displacement of a thin spherical shell of mass 20kg and diameter 1.0m, rotating about an axis through its center of mass, can be expressed as (theta)t=4.0t+5.0t^2-0.5t^3. (A) What is the angular velocity of the shell at t=2.0s? (B) What is the angular velocity at t-4.0s?
