Im really having problems with these force problems. It is much appreciated if you can help thanks!


1. A clerk moves a box down a horizontal aisle by pulling on straps attached to the box. The horizontal force is 250 newtons. The box is 35 kg. What is the coefficiant of kinetic friction?


2. What is the acceleration of a pillow that is being pulled 5 newtons in a 37 degree angle. The mass of the pillow is 1.0 kg?

3. what are the x and y componets of a 509 kg pumpkin inclined on 30 degree angle. (Assume the pumpkin is at rest)

hmmm are you sure question 1 is given all the information?

for question 2 you have a simple formula using newtons second law fnet = ma. So you have 5 - mgsin37 = ma now you just plug in your numbers and solve for a.

for question 3 very simple too all you need to know is what are components. The x component is mgsin(angle) just plug in your knowns and the y component is mgcos(angle) again just plug in your knowns. Simple as that

Hope that helps
