A particle is thrown upward from the ground. It experiences a constant air resistance which can produce a retardation of 2m/sec 2 opposite to the direction of the velocity of a particle. The ratio of time of ascent to the time of descent is {take g=10m/sec 2 }

Question

A particle is thrown upward from the ground. It experiences a constant air resistance which can produce a retardation of 2m/sec 2 opposite to the direction of the velocity of a particle. The ratio of time of ascent to the time of descent is {take g=10m/sec 2 }

Gowtham · Answer

time of flight is 2h/g time of ascent is h/g and time of descent is h/g for a normal journey if air resistant is considered during time of ascent both resistance and gravity acts downwards so time of ascent is h/(g+a) durind descent the air resistance acts upwards and gravity acts downwards so time of descent is h/(g-a) so the time of ascent/time of descent is g-a/g+a so ta/td=10-2/10+2 =8/12 =2/3
