- Find the resultant of these three forces. Note the angle give for F3 is the angle between F2 and F3; to find the angle to use to get F3's x and y components, add the given angles together. F₂ = 3150 N F3 = 3680 N 42.0⁰ 120.0° F₁ = 2550 NThree forces are applied to an object, as shown in the figure. Force ->F1 has amagnitude of 24.4 newtons (24.4 N) and is directed 30.0 degrees to the left of the (+) yaxis. Force ->F2 has a magnitude of 15.4 N and points along the (+) x axis. What mustbe the (a) magnitude and (b) direction (specified by the angle (theta) in the drawing) ofthe third force ->F3 such that the vector sum of the three forces is 0 N?In a two-dimensional tug-of-war, Alex, Betty, and Charles pull horizontally on an automobile tire at the angles shown in the picture. The tire remains stationary in spite of the three pulls. Alex pulls with force ₁ of magnitude 207 N, and Charles pulls with force Fc of magnitude 188 N. Note that the direction of Fc is not given. What is the magnitude of Betty's force if Charles pulls in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium? 142° Alex Charles Betty (a) Number i (b) Number i Units Units <
- A microscopic spherical dust particle of radius r and mass m is moving in outer space at a constant speed v. A wave of light strikes it from the opposite direction of its motion and gets absorbed. Part A) Assuming the particle decelerates uniformly to zero speed in time t, write an equation for the average electric field amplitude in the light.Write the solution on a paper and round to 4 decimal placesTwo forces acting at a point make angles 25° and 45° respectively with their resultant force which has a magnitude of 15N . Find the magnitude of the two components.
- Two rods and one cable are attached to the supports at O. If two of the forces are as shown, determine the magnitude F and direction of the third force so that the resultant of the three forces is vertically downward with a magnitude of 1160 lb. 1010 lb 45° 35° 430 lbA crate sits on a wooden horizontal surface (a wooden floor). The figure shows a top view of this looking down onto the crate (gravity would be acting into the page). Man one and man two apply forces F1 and F2, at angles of θ1 and θ2 respectively, with the goal of moving the crate in the x-direction. A resultant force of Fr = 30.5 lbs in the x-direction is required to accomplish this. All of the forces are in the xy plane. If man one applies a force of F1 = 21 lbs at an angle of θ1 = 16° from the positive x-axis, complete the following steps to determine the magnitude and angle of the force man two must apply. c) Combine these two equations to develop an expression for tan(θ2) in terms of Fr, F1, F2, and θ1. Remember that the crate does not move along the y-direction. d)Solve numerically for the value of θ2 in degrees. e)Using this value for θ2 and other known values, solve numerically for the value of F2 in lbs.a force F1=315N acts in the first quadrant at an angle of 70 degress above the x axis, while a second force F2=210N acts in the third quadrant at an angle of 40 degrees below the x axis. What is the magnitude of the resultant of these two forces. What is the direction (theta) of the resultant ?
