Question

1. How much net force is needed to make an 80-kg couch accelerate at 0.5 m/s/s?
2. A spoon is dropped off of a roof. If it hits the ground 2.5 seconds later...
(a) How far did the spoon fall?
(b) How fast was the spoon falling when it hit the ground?
3. In the diagram below (it's a box with forces going up, down, left, and right), the downward force (gravity) is 30 N, the force to the right, FR, is 80 N, and the leftward force, FL, is 40 N.
(a) How much support force acts on the box? (Hint: What must it be equal to?)
(b) Determine the net force on the box (it’s not zero!)
(c) What is the mass of the box, if the weight is 30 N? (Hint: what’s the weight of 1 kg?)

please show the work ** && you don't have to answer all of them you can just answer one of the questions <3 thankyouuu in advance
