(1) A 4m ladder has mass m= 10 kg. We assume that its centre of mass is half-way along its length. The ladder is leaning against a wall at an angle of 30° from the vertical, as shown in the figure. Suppose that the wall is frictionless smooth and slippery), and that the coefficient of static friction between the feet of the ladder and the floor is H. =0.6. Take the acceleration due to gravity to be g=10m/s" directed vertically...

A diving board has length of 1.8 m and a total mass of 65 kg.
However, the mass is not uniformly distributed, so its center of
mass is off center as shown in the diagram below. However, we know
that the moment of inertia around the center of mass is 20 kg m2.
The board is fixed to rotate around its far left end. A support
pushes up with a force of 750 N at the midpoint of the board...

Just question2(a) please. Thanks
2. An 10 kg object is hung from a spring attached to a fixed support. The spring constant of the spring is k = 40 N m-1. Suppose an external downward force of magnitude f(t) = 20e-2t N is applied to the object, and damping due to air resistance occurs with damping constant B = 40 N s m-1. Let y(t) denote the distance in metres of the object below its equilibrium position at time t...

A ball with mass m is attached to the end of a flagpole as shown in the figure below. The flagpole is connected to the side of a building at point P, has a length l, and makes an angle with the x-axis. (Consider the +x-direction to be to the right, the +y-direction upward, and the +z-direction to be out of the page.) At time t = 0, the ball becomes loose and begins to fall off of the flagpole...
Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor
Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N but friction prevents the crate from sliding. Part A Draw a free body diagram of the crate in the diagram below. Use the dot as the particle representing the crate and make sure to draw your vectors so that they have the correct orientation and their magnitudes...

1. A box (mass m = 20 kg) is
placed on a slope (LaTeX: \thetaθ = 40°), as shown in the diagram
below. The coefficients of friction between the box and the slope
are LaTeX: \muμs = 0.6 and LaTeX: \muμk = 0.4. The box is released
from rest on the slope.
Determine the acceleration of the box after it is released.
