As shown in the diagram, the 15-kg box B moves to the right at an initial velocity vo = 2 m/s when d = 0.7 m. A force F = 120 N along a specified direction is applied on the box during the entire motion of the box along a smooth floor. When the box reaches the spring at A, it starts k to compress the spring until it comes to a temporary stop. The spring constant is k =...

Problem 2: A ball spring system rotates on a table (Figure on the right). At time tl, the velocity in transverse () direction is measured to be Ve1 (known). The spring length was measured to be r and NOT stretched. This ball+spring system starts to rotate around the center and the radius will gradually increase. At time t2, the radius (length of spring) reaches r2 and stops elongation. Analytically evaluate the r as the function of VaLk (spring constant) by...

A 5 kilogram mass suspended from the end of a vertical spring stretches it by 1.225 metres. The system is placed in a medium offering a resistance (in Newtons) equal to 45 times the instantaneous velocity (in m/s). The mass is started in motion from the equilibrium position with an initial velocity of 1 m/s in the upward direction and with an applied external force F(t) 365 cos(3t) Newtons downwards. The displacement of the mass below the equilibrium position at...

The system shown consists of a rotating base, a 5kg ball with a
radius of 0.4m and a connecting link.The base is rotating about the
+z-axis with the angular velocity and acceleration shown.
Meanwhile, the link is rotating about a pin joint connected to the
base (aligned with the x-axis at the instant shown) with the
angular velocity and acceleration shown. If the link is 5m long
from the center of the pivot to the center of the ball, find...
