Question

Friction has th several rules, it would opposite the intended motion, and is generally less than the weight of e moving object, and once created in a motion there is always a pair of friction forces When a person walks forward, the feet would push on the floor backward while the floor would push the person forward. A 200 kg object on a smooth table was connected via a pulley to a vertically hanging weight of 490 Newton. 1a Find the acceleration 1b Find the tension 1c When the 200 kg was a 50kg top object glued onto a 150kg bottom object, find the minimum strength of the glue in Newton. 1d When the glue became 50% strength due to age ing, find the acceleration of the 150 kg object ie when the glue became 50% strength due to ageing, find the acceleration of the 50 kg object
