You want to move a heavy box with mass 30.0 kg across a carpeted floor. You pull hard on one of the edges of the box at an angle 30∘ above the horizontal with a force of magnitude 240 N, causing the box to move horizontally. The force of friction between the moving box and the floor has magnitude 41.5 N .   1. What is the box's acceleration just after it begins to move?  2. Draw a free body diagram for the box, assuming that the positive-x axis is to the left, and the positive-y axis is upward.

Two blocksmịand m2 connected by a rope are being pulled by a horizontalforce F equal 160 N.

A 7.8 kg object undergoes an acceleration of 2.9 m/s^2 A. What is the magnitude of the resultant force acting on it? N B. If this same force is applied to a 4.7kg object, what acceleration is produced? m/s^2

A student attaches a rope to a 32 kg box, and drags it to the left with constant velocity of 1.97 m/s. The tension in the rope is 207 N at an angle of 35.7° to the ground. How much does the box weigh? Find the x and y components of the applied (tension) force: Fx = N. %3D Fy = N. How much friction must be present? How much Normal force must be present? N.

A cardboard box rests on the floor of an elevator. The box has a mass m = 2.75 kg and the elevator has an upward acceleration of a.   a.  Write an expression for the sum of the forces acting on the box in the y-direction, ΣFy, given that up is the positive y-direction. Your answer should be in terms of FN, m, and g.  b. Write an expression for the normal force, FN, that the block experiences in terms of the elevator's acceleration, the block's mass, and the acceleration of gravity.  c.  If the elevator's acceleration has a magnitude of g in the downward direction, what would the normal force, FN1 be in Newtons?  d.If the elevator's acceleration had a magnitude of g in the upward direction, what would the normal force FN2 be in Newtons?

I need help with part a of the question

A teenager of mass m1 = 56 kg pushes backwards against the ground with his foot as he rides his skateboard. This exerts a horizontal force of magnitude F foot = = 18.5 N. The skateboard has m2 = 2.6 kg. a. Write an expression for the magnitude of the horizontal component of force that the ground exerts on the teenagers foot, F ground. b. Write an expression in terms to given quantities for the magnitude of the skateboard acceleration, a , while the teenager is pushing backwards on the ground? c. What is the numerical value of the magnitude of the acceleration, a, in m/s square?

You walk into an elevator, step onto a scale, and push the "up" button. You recall that your normal weight is 625 N. Draw a free-body diagram. When the elevator has an upward acceleration of magnitude 2.50 m/s2, what does the scale read? If you hold a 2.25 kg package by a light vertical string, what will be the tension in this string when the elevator accelerates as in the previous part?
