a body moving with uniform acceleration travels 84m in the first 6s and 180m in the next 5s.find th initial velocity and acceleration
sreedhar2:
total time = 5+6=11s
acceleration = v2-v1 / t = 36-14/11 = 22/11 = 2m/s²
i got to know the answer
by using the law of motion S=ut+1/2at^2
i got u=14 -3a and u=24-11/2*a
i dont know how..
by substituting rhs i got a=4ms^-2 and v=2ms^-1
what is my mistake?
you didn't use laws of motion but you did your best good luck
but.. you got different answer

and when you solve it further I think you got -10.2 acceleration
