an elevator weighing 500kg f moving upward and tension in the supporting cable is 50000N.find upward acceleration.

a bullet moving with a velocity of 100m/s pirces a block of wood and moves out with velocity of 10m/s.if thickness of the block reduces tn one half of the previous value what will be the emerging velocity of bullet

a constant force acts for 3s on a body of mass 16kg and then ceases to act.during the next 3s,the body covers 81m.find the magnitude of the force.

a body displaced 12m due to east then 5m due to north then 9m vertically upward what is the resultant displacement?

give the reaction when lead nitrate is heated

Resultant displacement from 12m east to5m north to9m vertically upward

calculate the work done in lifting a 300N weight to a height of 10 m with an acceleration 0.5m/second square.
