A person throws a 2.50 lb stone into the air with an initial upward speed of 15.0 ft/s . Part B Make a free-body diagram of the forces for this stone at its highest point.(Draw the force vectors with their tails at the origin of the coordinate system.) Part C Make a free-body diagram of the forces for this stone when it is traveling downward. (Draw the force vectors with their tails at the dot.)

can u help with part b

y Problem 3: The diagram shows the all of the forces acting on a body of mass 2.31 kg. The three forces have magnitudes F₁ = 50.6 N, F2 = 20.8 N, and F3 = 75.8 N, with directions as indicted in the diagram, where 0 = 39.6 degrees and p = 30.1 degrees. The dashed lines are parallel to the x and y axes. At t = 0, the body is moving at a speed of 7.93 m/s in the positive x direction. Part (a) What is the x component of the acceleration in m/s²? ax = || Ę Lª F $ F

Please help me to answer this. Answer only Number 7

A robot pushes a 20-kg box on the horizontal surface as part of the moving job, the force is 35 N to the left shown. The box does not move. The coefficients of friction between the floor and box are µs = 0.75 and µk = 0.40. Use g = 10 m/s². Match the anwers with questions. (Hint: Draw a proper free-body diagram.) ◆ What is the magnitude and direction of the pushing force on the box from the hand? What is the magnitude and direction of the weight force on the box from the earth? ◆ What is the magnitude and direction of the normal force on the box from the floor? A A What is the magnitude and direction of the friction force on the box from the floor? What is the net force on the box? A. 200 N, to the left B. 200 N, down C. zero, therefore no direction D. 35 N, down E. 35 N, to the left F. none of the given G. 35 N, to the right H. 200 N, up 1. 35 N, up J. 200 N, to the right
