- Please explain how to do the following questionarrow_forwardA 100. N force is applied to a 21.2 kg crate to slide it along a rough horizontal surface. The diagram shows the forces acted on the crate in this situation. What was the magnitude of the normal force acting on the crate? (a) 208 N (b) 258 N (c) 121 N (d) 69.6 N (e) 158 Narrow_forwardDetermine the resultant ?R of the three tension forces acting on the eyt bolt. Find the magnitude of R and the angle θx which R makes with the positive x-axis. Note that F1= 563 N, F2= 345 N and F3= 296 N.arrow_forward
- Two forces, F and Fact on the 7.00-kg block shown in the drawing. The magnitudes of the forces are F₁-49.7 N and F₂=33.2 N. Take the positive direction to be to the right.

(Assume east and north are directed along the +x-axis and +y-axis, respectively.) (a) What is the magnitude of the net force (in N) on the object? (b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)arrow_forwardCalculating Net Force Two forces act on an object: 1) a force of magnitude F₁ and direction 0₁ 2) a force of magnitude F2 and direction 02 The net force on the object has a magnitude of Fnet and a direction of Onet. Solution: Forces must be added in component form (x and y separately): Fnet,x=F₁ cos 0₁ + F₂ cos 0₂ = Fnet CoS Onet Fnet.y Fnet sin net The 2 equations above have 6 variables. So if 4 variables are given, the equations can be solved.
