We just did a lab in Physics titled "Work and Energy", and we basically took a weight of different masses (m1 and m2) and attached it to a car(mass of car = 0.461 kg) on an incline of 30 and 45 degrees. The distance the car traveled is 0.302 m, which is also the change in y for the weight suspended in the air. We calculated the work of friction by formulas given in the book (f = mcg sin...
1. A 185 g cart is given a quick push up a frictionless incline, giving it an initial velocity of 1.45 m/s. The incline is at an angle of 10.0 to the horizontal. You must show your work to get full credit for this problem. a) What is the cart's initial kinetic energy, i.e. when it leaves the launcher? KE =mv eay @ztty =C85k9)(145s) = .1343 b) What is the cart's change in kinetic energy (Kr-Ko) from the launch point...
The car shown supports it the total weight and the rear tire carries 60%. The car is on an incline having an angle o( with the horizontal X-axis. The coefficient of friction between the tires and ground is μ Given that W-3500 lbs and H 0.35 s weight "W" on its tires such as the front tire cames 40% of a) If both tires are locked with brakes, what is the maximum angle oc of the incline such as the...
a) Assuming that f=μN, show that the coefficient of (rolling) friction for the car moving down the inclined plane with a constant speed is gived by μ=m2/mccosθ. Use symbols, not numbers. b)Prove that θ is equal to μk when the blcok sldies down the incline with a constant speed?(use symbols not numbers) b2) if θ is the maximum angle of inlcline justbefore theblcok moves, what is μs in term of θ? c)suppose that the blcok were made to move up...
Could you please show your work as well? Thank you!
The weight of the block in the drawing is 68.5 N. The coefficient of static friction between the block and the vertical wall is 0.400 Block (a) What minimum force F is required to prevent the block from sliding down the wall? (Hint: The static frictional force exerted on the block is directed upward, parallel to the wall.) (b) What minimum force is required to start the block moving up...
А D z Problem 3. Work done by gravity and change in gravitational potential energy In problem the box was moving in a horizontal direction, and therefore no work was done by gravity. Here, we will analyze a situation where the force of gravity has some component that points along the direction of the displacement, and therefore there is non-zero work done by gravity on the system of interest Consider a box of mass 10 kg, initially at rest, which...
Please explain steps for part d. I cannot figure it out A box, with a weight of mg = 25 N, is placed at the top of a ramp and released from rest. The ramp measures 4.20 meters horizontally and 3.30 meters vertically. The box accelerates down the incline, attaining a kinetic energy at the bottom of the ramp of 48.0 J. There is a force of kinetic friction acting on the box as it slides down the incline. a)...
Indicate whether each item is true or false. If an item is false, please correct it so that it is true. Speed is a scalar quantity. Work and energy are vector quantities. Objects that are not moving cannot have any work done to them. Pressure is uniform throughout a fluid, regardless of depth Density of a material changes as the temperature of the material changes. Solids are always more dense than liquids. Liquids are always more dense than gases Falling...
