Question

The figure shows the velocity graph of a75 kg passenger in an elevator. a)What is the passenger's apparent weightat t= 1.0s? Express your answer using twosignificant figures. b)What is the passenger's apparentweight at t= 5.0s? c)What is the passenger's apparent weight att= 9.0s? a)What is the passenger's apparent weightat t= 1.0s? Express your answer using twosignificant figures. b)What is the passenger's apparentweight at t= 5.0s? c)What is the passenger's apparent weight att= 9.0s? c)What is the passenger's apparent weight att= 9.0s? c)What is the passenger's apparent weight att= 9.0s? The figure shows the velocity graph of a75 kg passenger in an elevator. a)What is the passenger's apparent weightat t= 1.0s? Express your answer using twosignificant figures. b)What is the passenger's apparentweight at t= 5.0s? c)What is the passenger's apparent weight att= 9.0s?

Explanation / Answer

the downward force of gravity            Fgrav = mg    m= mass of the passenger    g =acceleration due to gravity          net forceacting on the passenger            Fnet = m a    acceleration a = velocity / time          Fgrav + Fnormal =   Fnet     Fnormal =   F net  -   Fgrav         since normal forceis equal to apparent weight      plug the values and get theanswere
