Two horizontal forces F= 70NÎ + 20NĴ and F= -30NÎ
+ 40Nj, are pulled a 12
body that is stuck in a field. The forces pull the body
producing the vector forces shown in the figure.
Find the direction and magnitude of the horizontal
component of a third force on the body that will
make the vector sum of forces on the body equal to
zero.
Four forces act at point A, and point A is in equilibrium. What is the force vector P.

- Hand-written, step-by-step solution, please. Thank u!arrow_forwardA contestant in a winter sporting event pulls an m kg block of ice across a frozen lake by applying a force F at an angle θ above the horizontal as shown. Assume that the coefficient of static friction for ice on ice is 0.0300, and the coefficient of kinetic friction for the same is 0.0100. Let to the right be the positive x direction and up be the positive y direction for your equations. Obtain a numeric value, in newtons, for the magnitude of the maximum applied force, F, consistent with static friction when the force makes an angle 22° above the horizontal and the mass of the block is 34 kg. Obtain a numeric value for the acceleration, a, in meters per squared seconds, when the mass of the block is 34 kg and the angle of the rope is 22° above the horizontal.arrow_forwardA 781 N sprinter can push his feet back against the starting blocks with a force of 1852 N in the horizontal direction.
