If you are applying an upward force of 3.0 N to a book weighing 2.0N, the normal force on your hand due to the book is:

2.0 N downward

1.0 N downward

2.0 N upward

3.0 N downward

An object weighing 4.00N is resting on a platform. The platform (and object) start from rest and reach a velocity of 12.0 m/s upward in 48.0m.

a) Describe the FBD for the object. Be sure to include the Name, direction, and relative size of each vector.

b) Determine the acceleration of the object.

c) Calculate the value of the normal force acting on the object?

d) What force must be equal to the 4.00 N weight.
