F1 acts on the object at the direction of 0 = 60.0° with a magnitude of 7.20 units and F2 acts on the object in the direction of the positive y-axis with a magnitude of 4.50 units. Find the magnitude and the direction of the resultant force of F1 and F2.arrow_forward
- Suppose that w = 350 N/m A) Determine the x and y components of force which the pin A exert on the frame using scalar notation. B) Determine the x and y components of force which the pin B exert on the frame using scalar notation.arrow_forwardExplain why internal forces, or those that act within the system of interest of the object under consideration, are not relevant in solving problems related to the Second Law of Motion. A net external force has no effect in the change in motion. Internal forces, or those responsible for holding a given object together, affect the motion of such an object. A net external force causes a change in motion. Internal forces, or those responsible for holding a given object together, do not affect the motion of such an object. A net internal force causes a change in motion. External forces, or those responsible for holding a given object together, do not affect the motion of such an object.arrow_forwardConsider a pair of forces, one having a magnitude of 20N and the other magnitude of 12N .What maximum net force is possible for these two forces? What is the minimum net force possible?arrow_forward
- 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.arrow_forwardThe driver of a 1250 kg car traveling at a speed of 17.5 m/s applies the car’s brakes when he sees a red light. The car’s brakes provide a frictional force of 8250 N. Determine the stopping force of the car.arrow_forwardProblem 5: An object of mass m has these three forces acting on it (there is no normal force, "no surface"). F = 3 N, F2 = 10 N, and F3 = 5 N.

- A book of mass M rests on a table. A block of mass m is placed on the book, as shown in the figure below. m g What can be said about the normal force exerted by the table? O The table exerts normal force (M+m)g on the book and normal force mg on the block O The table exerts normal force Ma on the book and normal force mg on the block O The table exerts normal force Mg on the book O The table exerts normal force (M+m)g on the bookarrow_forwardWhen a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 25 kg, the acceleration of the object Is 3 m/s. When the same force acts upon another object, its acceleration is 5 m/sf. What is the mass of this object?
