Question # A particle starts with initial speed u and retardation a to come to rest in time T. The time taken to cover first half of the total path travelled is

# A particle starts with initial speed u and retardation a to come to rest in time T. The time taken to cover first half of the total path travelled is

(1) ( frac{T}{sqrt{2}} )

(2) ( Tleft(1-frac{1}{sqrt{2}}right) )

(3) ( frac{T}{2} )

(4) ( frac{3 T}{4} )

Solution

Option (2) ( Tleft(1-frac{1}{sqrt{2}}right) ) is correct answer. Check details solution above.
