If FTL is 56 N, FW is 100 N, and the box is not moving, what is FTR?
44N
Beacuse Upward Forces should balance downward Forces.
FTL + FTR =FW
56+FTR =100
FTR = 100-56
= 44
BOX is not moving so forces acting on boxes are in equlibrium or in balance so just balance all the forces
Fw = Ftl+Ftr
this in balance
so
100 N = Ftr +56N
Ftr = 44N
A box weighing 100 N is placed on the floor of a truck moving 60 km/hr horizontally. if the coefficient of friction between the box and the floor of the truck is 0.5, determine how far the truck move before the box stops slipping.
A constant 74.6-N force acts on a 4.99-kg box. The box initially is moving at 15.1 m/s in the direction of the force, and 2.93 s later the box is moving at 76.5 m/s. Determine the work (in J) done by this force. You may assume that the box experiences constant acceleration, but do not assume that only one force acts on the box.
A force of 60 N is required to start a 10kg box moving across a horizontal floor. (a) What is the coefficient of static friction between the box and the floor? (b) If the 60 N force continues, the box accelerates at 3m/s^2. What is the coefficient of kinetic friction? P.S please write the right equations and answers asap!!
4. A constant 80-N force acts on a 5.0 kg box. The box initially is moving at 20 m/s in the direction of the force, and 3.0 s later the box is moving at 68 m/s. Determine both the work done by this force and the average power delivered by the force during the 3.0-s interval. Ans: W=11kJ, P= 3.5kW
In the figure is represented a box with all the forces acting on it. If the force of friction is 20.0 N, what is the net force acting on the box in magnitude and direction? The mass of the box is 10.0 kg. F-48.0 N Ftr mg
A box weighs 60 N and is sitting on a horizontal frictionless floor. A 100 N force pulls the box at an angle 30 degrees above the horizontal. What is the normal force of the box?
A 100 N force is applied to a box at an angle of 60° to the horizontal via a rope. How much force “lifts” the box and how much “pulls” it along the surface? a. 86.6 N; 50 N b. 100 N; 100 N c. 50 N; 50 N d. 50 N; 86.6 N

a box (m=0.830) is moving on a horizontal surface with a coefficient of friction of 0.108. a spring with a spring constant of 17.3 N/m is 1.95m from the box. the box is stopped by the spring, compressing it 0.105m what is the initial speed of the box and how fast the box moving when it reaches the spring
A 50 N force keeps a box (m=20 kg) moving across a surface at a constant speed (v =3 m/s). If this force is applied for 30m, what is the change in the objects thermal energy?
