A force Fis said to be conservative if the work done is independent of the path followed by the force acting on a particle as it moves from A to B. depends only on the initial and final positions of the particle is independent of its velocity or acceleration. all of the above does not depend on the initial and final positions of the particle.

You pull on a string with a horizontal force of magnitude F = 59 N that is attached to a block of mass m = 6.3 kg, then to the axle of a solid cylinder of mass mc = 5.9 kg and radius r = 0.4 m, then to a spring of spring constant k = 145 N/m. This is all done on an inclined plane where there is friction (μ = 0.63 and μ = 0.36), and the incline angle is 0 = 28 degrees. Everything starts at rest, and the spring is unstretched. The block slides down the plane, the cylinder rolls down the plane (without slipping), and the spring stretches. k bllllllll b 0 Fyb

Q1. Two asteroids collide and stick together. The first asteroid has mass of 15×10³kg and is initially moving at 770 m/s. The second asteroid has mass of 20×10³kg and is moving at 1020 m/s. Their initial velocities made an angle of 20° with respect to each other. What is the final speed and direction with respect to the velocity of the first asteroid?

.Q21 The forces do not cause rotation

True or false Statics mechanics allows us to represent distributed loads as a concentrated force located at the centroid of the distributed load.

A block is pulled at constant speed along a rough level surface by a ropc that makes an angle of 30° with respect to the horizontal. The applied force along the rope is P . The force of kinetic friction between the block and the surface is 20 N. 30° Which one of the following expressions gives the magnitude of the force P in SI units? O 20(sin 30°) O 10(cos 30) O tan 30 O 20/(cos 30) O 30/(sin 30°) O O O O O

TRUE OR FALSE 1. Two parallel forces acting on the same plane will always be concurrent. 2.  A free body diagram includes all forces that are not directly acting on a body.

a.) What is the angle, measured relative to the positive x-axis, of the load's acceleration? (The correct answer is: -10.219 degrees) Just need the steps to get there  b.) Three horses pull and guide a 132 kg payload down a river, exerting the forces shown in the figure, with F1 = 29 N, F2 = 38 N, F3 = 58 N, θ1 = 30°, and θ2 = 60°. What is the magnitude of the payload's acceleration? (The correct answer is: 0.7861 m/s^2)Just need the correct steps to get there
