In order to calculate the minimum amount required, we will first round
the below-minimum-balance fee to $10. Next, we will use the equation:
A = I * (IR)^n, where A is the amount after n years and I is the initial investment and IR is the interest rate per year.
10 = I*(0.0001)^1
I = $100,000
$100,000 must be in the account to cover the minimum fees.
The reaction force exerted by the floor of the elevator on the man is D.944 N
Step-by-step explanation:
When the elevator is accelerating upwards at 2 m/s² there occurs a fictitious force acting downwards to produce a downward acceleration of 2 m/s².
The formula to apply here is ;
Weight due to gravity=mg where m is mass of the man and g is acceleration due to gravity.
Due to additional downward acceleration the total acceleration downwards will be : 9.8+2 = 11.8 m/s²
The man weighs down on the elevator floor with a force of ;
F=m(a+g) where m is mass of man, a is acceleration
F=80( 9.8+2)
F=80(11.8)= 944 N
The reaction force by the floor of the elevator is thus 944 N
