A spring system in simple harmonic motion has a mass=4kg and k=9N/m.
(a) At time=0s, the block is offset from its equilibrium position and released from rest. Determine the trajectory of the block, x(t), when its initial displacement from equillibrim is (i) 5m/s and (ii) -5m/s.
(b) The block is offset from its equilibrium position at time t=0s. Determine the trajectory, x(t), of the block when its initial velocity, v0, is equal to (i) 5m/s and (ii) -5m/s
(c) At time=0s, the block is offset from equilibrium position by 5m and is in motion with velocity v0=5m/s. Determine the trajectory of the block.
Three forces of magnitudes F1 = 4.0 N, F2 = 6.0 N, F3 = 8.0 N, F4 = 5.0 N, and F5 = 5.0 N are applied to a block of mass m = 3.0 kg, initially at rest, at angles shown on the diagram. (Figure 1) All angles should be measured from the positive x ax..
Cells maintain a high concentration of macromolecules inside them. How do you expect this to affect the osmotic pressure inside the cell? What mechanisms does the cell use to counterbalance osmotic pressure? What are "depletion forces" and why are..
