Question 9 of 15 -15 : View Policies Current Attempt in Progress Two individuals are attempting to relocate a sofa by applying forces in the indicated directions. If F₁ = 330 N and F2 = 450 N, determine the vector expression for the resultant R of the two forces. Then determine the magnitude R of the resultant and the angle 0 which it makes with the positive x-axis (measured counterclockwise from the x-axis). I 68° 1 F₁ Answers: B 4) ENG B |||

2. A uniform rectangular block is attached to a cart that is accelerating up a 20° incline at 3 m/s². The block is attached to a cart by a hinge at Point A and a roller at Point B. a. What is the force that the roller is applying to the block at Point B? b. What is the force that the hinge is applying to the block at Point A? Y a = 3 m/s² х 20° 0.8 m m= 100 kg B 0.6 m 1.0 m g
