A package is thrown down an incline at A with a velocity of 1 m/s. The package slides along the surface ABC to a conveyor belt which moves with a velocity of 2 m/s. Knowing that d = 6 m and µk = 0.2 between the package and all surfaces, determine (a) the speed of the package at C, (b) the distance the package will slide on the conveyor belt before it comes to rest relative to the belt

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
