Friction force in two books
WebFriction. When two surfaces slide against each other, a force called friction makes them stick very slightly together. Smooth surfaces, like ice and glass, are easy to slide over. They create very little friction. Rough surfaces like rock and sand create much more friction, and are easy to grip on to. It is harder to move things when there is a ... WebSep 12, 2024 · A 50.0-kg crate rests on the bed of a truck as shown in Figure 6.5. 5. The coefficients of friction between the surfaces are μ k = 0.300 and μ s = 0.400. Find the frictional force on the crate when the truck is accelerating forward relative to the ground at (a) 2.00 m/s 2, and (b) 5.00 m/s 2.

WebSolution: On a flat surface, the normal force on an object is N = mg. Using this, we can calculate the force of friction as follows: F = μN F = μ mg Substituting the values in the equation, we get F = (0.400) (40.0 kg) (9.80 m/s 2) F = 156.8 N. The frictional force acting on the boat is 156.8 N. Web21. Two teenagers are pulling on ropes attached to a tree. The angle between the ropes is 30.0°. David pulls with a force of 400.0 N and Stephanie pulls with a force of 300.0 N. (a) Find the component form of the net force. (b) Find the magnitude of the resultant (net) force on the tree and the angle it makes with David’s rope.
