Anoop pushes eight identical blocks on the horizontal frictionless surface with horizontal force F. the that block-1 (where F is applied) exerts on block 2 has magnitudes F21 and the force that block-7exerts on the block -8 is F87. Find F21/F87

A block is projected upwards on a rough inclined plane at 20 m/s. let the time in going up then t is equal to
