25. Two equal forces acting on an object in opposite directions will be in equilibrium A. only if they act on the same point on the object. B if they are separated by a distance. C when they are balanced by a third force. D when their moments about the same point are equal. 相关...
(b) What is the mass of an object if it took 270 J of work to move it 15 m? An object moved 2 meters upward while a force of 3 newtons to the left at right angles to the displacement acts. No other forces act on the object. What is the work d...
2. Two forces, F1 and F2 act on an object and the angle between them is 60 degrees. Determine the magnitude and the direction of the resultant force FR relative to F1 if F1 = 50 N and F2 = 30 N. Two forces wit...
<p>To find the maximum resultant force when two forces of 12 N and 8 N act on a body, we can use the formula for the resultant of two vectors. The maximum resultant occurs when the two forces are acting in the same direction.</p><p>1. <strong>Identify th
Resultant Force Two forces of magnitude 40 newtons (N) and 60 N act on an object at angles of 30^( ° ) and -45^( ° ) with the positive x-axis, as shown in the figure. Find the direction and magnitude of the resultant force; that is, find _1+_2....
The total number of forces acting on an object is two. The object is in equilibrium. Which statements about the forces are correct?1 The two forces must have equal magnitudes.2 The two forces must act in the same direction.3 The two forces must act through the same point.A 1 and 2 ...
Answer to: Two forces act at an angle of 120 degrees. The bigger force is 40 N and the resultant is perpendicular to the smaller one. Find the...
Forces are commonly described as a push or a pull that causes the acceleration of an object. When the contact between the two objects stops, the two objects no long experiences the force.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now Create ...
If an object has no forces on it, and then you apply a force by, for example, pushing it, the object will accelerate. An acceleration is a change in the velocity of an object over time. So if the forces on an object are unbalanced, the object's velocity will change. ...
