1- (KINETICS) An elevator weight 25 KN and is moving vertically downwards with a constant acceleration. Write the equation of the elevator cable tension. Starting from rest it travels a distance of 35 m during an interval of 10 s. Find the cable tension during this time. Neglect all other resistances to motion. What are the limits of cable tension?

F A block of mass of 2kg is being pushed by of force F = 10 N at an angle of 0 = 30° to the horizontal. If the block starts from rest, what is its speed after it has travelled 5 meters Without friction, v = m/s With μk m/s - With Uk m/s 0.25, v= What if it starts with an initial speed of 5 m/s Without friction, v = m/s = BY UBC Engineering 0.25, v=

A small block (2.25kg) travels along a frictionless path at a speed (6m/s) before it reaches a frictionless semi circular path with a radius of 0.5m. 1) at point A, what is the force exerted by the track on the block? 2) the bottom of the track has a length of 15m with friction. Determine the coefficient of kinetic friction between the block and the bottom of the portion of the track if the block just makes it to point B before coming to rest.
