A box is resting on a table
frictionless). Determine the weight of the box and the normal force acting on it.
(a) If the box was pushed down, with a force of 40N, determine again the normal force acting on the box.
(b) If the box was pulled up with a force of 40N, what now is the normal force on the box?
-Can you please use Newton's Laws and equations to help explain how to solve this problem. im lost, but thank you for any help. =)
Hey do you go to proyecto? =]
Look to the response to Jodie!
