1) Force acting on the object is 6 N. The object is moving with acceleration of 3 m/s. When the object's acceleration is doubled, the net force would be, A) 3N B) 6N C) 9N D) 12N E) I8N 2) A push of magnitude P acts on a box of weight Was shown in the figure. The push is directed at an angle 0 below the horizontal, and the box remains a rest. The box rests on a horizontal surface...
helpp!!! Work Done by Different Forces (No Calculator): You try F or N Normal Force perpendicular to the surface. Q1: The block in the figure is moving upwards along a smooth inclined plane at angle 0. A force F is pushing it upwards, parallel to the incline as shown in the figure. The block moved a distance, d. (a) Draw a FBD and (b) figure out work done by forces F.F. fand N fFriction FA Applied force. Force towards the...
1) An object is in static equilibrium. Which statement(s) about this object must always be true? A) The net force on the object is zero. B) The acceleration of the object is zero. C) No forces are acting on the object. D) Both A and B E) All of these 2) A large fast-moving truck collides with a small stationary car. During the collision A) the car and the truck have the same magnitude of acceleration. B) the magnitude of...
Renee is on Spring Break and pulling her 21-kg suitcase through the airport at a constant speed of 0.47 m/s. She pulls on the strap with 120 N of force at an angle of 38° above the horizontal. Assume the ground to be flat, Draw a FBD showing the forces on the suitcase. Find the acceleration of the suitcase. Determine the normal force experienced by the suitcase. Determine the total resistive force (friction) experienced by the suitcase. Find the coefficient...
Work Done by Normal Force Consider an object sliding along the surface shown below. Choose and show a direction of motion for the object and show the direction of the normal force. Use this figure to do the scalar product given below. oM bns av W, n-s Is the work done by the normal force exerted between two colliding objects also zero? Explain. Work Done by Weight Unlike the normal and kinetic friction forces, the direction of an object's motion...
MULTIPLE CHOICE, Show your work in the space provided, Circle the correct answer 1. An object is moving with constant non-zero velocity. Which of the following statements about it must be true? As shown in the figure, a woman is straining to lift a large crate, but without success because it is too heavy. We denote the forces on the crate as follows: P is the magnitude of the upward force being exerted on the crate by the person, C...
1. A kid is pulling on a lawnmower with an applied force FA that is 30° with respect to the horizontal. Which statement is true about the normal force acting on the lawnmower? (5 pts) A. The normal force acting on the block N = 0, 300 B. The normal force acting on the block N < mg. C. The normal force acting on the block N > mg. D. The normal force acting on the block N = mg....
Consider the ladder in 8.15. Compute the normal force again, assuming a 75 kg man is standing on the ladder (a) at its midpoint and (b) four fifths of the way up the latter. I posted this question earlier but was very confused on how it was answered and laid out. I am not understanding how to go about this or what formulas to use. I know the answers is (a) 130.95 N and (b) 194.2 N but I do...
Phys 222 Worksheet 1 Forces and Kinematics . In a local bar, a customer slides an empty beer mug down the counter for a refill The height of the counter is 1.14 m. The mug slides off the counter and strikes the floor 0.40 m from the base of the counter (a) With what velocity did the mug leave the counter? (b) What was the direction of the mug's velocity just before it hit the floor? 2. A placekicker must...
