What is everything that you can say about the net force acting on a crate that...
a nonzero external net force acts on a particle. What can you say about the momentum of the particle?
A large crate filled with physics laboratory equipment must be moved up an incline onto a truck. The crate is at rest on the incline. What can you say about the force of friction acting on the crate? A. the frictional force points up the incline B. the frictional force points down the incline C. the frictional force is zero A physicist attempts to push the crate up the incline. The physicist senses that if he applies slightly more force...
QUESTION 1 A crate at rest resting on a floor: Normal force direction will be: along the angle of the ramp with respect to the horizontal towards the center of earth parallel to the surface of the ramp perpendicular to the surface of the ramp 1 points QUESTION 2 A box is at rest on a wooden surface. The frictional force direction in this case will be: Opposite to the direction of the applied force perpendicular to the surface...
A crate rests in the rough bed of a truck. When the truck accelerates to the left at a constant rate, what is the direction of the friction force acting on the crate? (You can assume that the crate doesn't slip in the bed of the truck.) To the right It can't be determined There is no net friction force. ● To the left Submit Answer Tries 0/2 What is the direction of the friction force acting on the truck,...
What can you say about the value of the static friction force between two surfaces if the contact area is changed?
For an object in uniform circular motion, what can you say about the directions of the velocity, acceleration, and net force vectors? The velocity vector is perpendicular to the acceleration vector; the acceleration vector is parallel to the net force vector. The velocity vector is parallel to the acceleration vector; the acceleration vector is perpendicular to the net force vector. The velocity vector is perpendicular to the acceleration vector; the acceleration vector is perpendicular to the net force vector. The...
What other forces (at least 2) are acting on that crate? Draw and Label the 2 forces on the diagram. 5. Two horizontal forces, as shown in the diagram, are exerted on a 10 kg crate: a 70 Newton applied force and a 30 Newton frictional force. What is the magnitude and direction of the crate's acceleration? BONUS QUESTION: What other forces (at least 2] are acting on that crate? Draw and Label the 2 forces on the diagram.
what is the net force of a 2.0 N force and an 3.0 N force acting on an object in the same direction? What is the net force of a 2.0 N force and an 3.0 N force acting on an object in the same direction?
A 40 kg crate is pulled 50 m along a horizontal floor by a constant force exerted by a person, Fp = 150 N, which acts as 30 degree angle. The floor is rough and exerts a friction for Ff = 40 N. Determine: a) the work done by each force acting on the crate b) the net work done on the crate
At what angle must a force of 505N be applied to a crate if the net work required to move the box 12m is 4550J?
