Solve ques no. 2 with step by step solution

EG 231 Assignment QUESTION 1 Chisekeseke mine uses conveyor belts to transport copper pallets from point A to point B. usually, these conveyor belts are inclined at an angle of 15° at all times with respect to the horizontal. A student from the Copperbelt Uhiversity on industrial attachment places a copper pallet on the conveyor belt. The conveyor belt is moving with a velocity of 2.5 m/s and the pallet is initially at rest. Determine the time required for the pallet to come to rest on the conveyor belt if the coefficient of kinetic friction between the pallet and the conveyor belt uR 0.32. QUESTION 2 A group of renowned Engineers at Kwepe Astronomy, have successfully place a Dimbwi Satellite in a circular orbit. The Dimbwi satellite has a mass of 400kg and the orbit where it is placed is at a distance of 1500 km above the surface of the earth. At this elevation, the acceleration of gravity is about 6.4 m/s2. If the orbital speed of the Dimbwi Satellite is 25.6 x 103 km/h, find the linear momentum of the Dimbwi Satellite.

Explanation / Answer

2. Linear momentum is the product of mass with velocity.

Therefore Linear momentum = 400 Kg x (25.6 x 103 x 5/18 m/s) = 2.84 x 106 kg m/s Answer
