A boy with a mouse is 80 kg stands on a scale in an ascending elevator with an acceleration of 3 m/s What is the resultant upward force acting on the boy due to the motion of the elevator

Upward force on the boy will be 1024 N      

Explanation:

We have given mass of the boy m = 80 kg

Acceleration due to gravity

It is given that elevator is ascending with acceleration of

So net acceleration on the boy = 9.8+3 = 12.8 ( As the car elevator is moving ascending )

So upward force on the boy will be equal to F = m(g+a)

So

So upward force on the boy will be 1024 N

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
