hi , pls help me understand how this is solve. thank you so much a) a dictionary is pulled to the right at constant velocity by a 10N force acting 30 degrees upward above the horizontal. the coefficient of kinetic friction between the book and the horizontal surface is 0.5. what is the weight of the book? also, pls draw a diagram with proper labels for added information so I can understand it fully. thanks again

Hi there, I cannot seem to figure out this question. I got an answer of 14.04 but it is incorrect. Can someone help walk me through this question? A vendor at the local art fair ties her tent to the concrete-filled coffee can shown in the picture below. A stiff breeze comes up and the string becomes taut. What is the maximum value the string tension can have before the can slips? The coefficient of static friction between the can and the ground is 0.36. Thank you!

(a)If the string makes an angle 20.0 degrees with respect to the vertical, what is the acceleration a of the van in m/s2? (b) What is the tension in the string in newtons?
Once you reach the 21st floor you decide that your urge to understand physics is too great so you decide to ride the elevator back to the ground floor to analyze what happens. The elevator accelerates downward at 2 m/s2. What is the Gravitational Force? Since the elevator is accelerating downward does the Normal Force have to be greater than, equal to or less than the Force of Gravity? Are the forces balanced or unbalanced? Draw a free body diagram of the forces acting on you. Be sure to draw the size of your arrows appropriately. What is the Net Force, using Newton’s 2nd Law, while the elevator is accelerating downward? What is the Normal Force? What does the scale read as the elevator is accelerating downward
Does changing the mass of the object affect the acceleration? I was to conduct an experiment where the motion of an object sliding on an inclined air track under the influence of gravity is observed. In order to demonstrate the effects of force while minimizing friction, the air track has lines of holes drilled along the top faces. My thought process: because f=ma I thought yes, but I have also gathered data that shows me that increasing mass does not necessarily mean increasing/decreasing a.
When a force equal to its weight is applied to a body free to move by pushing, pulling, or lifting an object, what is its acceleration? Why? Justify your answer do not copy from google or i will downvote
Chloe is helping Tina move. Tina has to load a 265 kg box of chocolates and coffee up an incline of 25o, which also has a coefficient of static friction of 0.50. Chloe applies a force on the box at an angle of 30o with respect to the ramp. What is the minimum force needed to slide the box up the ramp? I know the answer is 2037.93N 30degrees up respect to the ramp but I dont know the steps to solve it.
