⦁ Use the equation of motion to show that once released from submersion the magnitude of the acceleration a, for the object that ascends (floating to the surface), in terms of the density of the fluid and object is:

a = (ρoil /ρo – 1)g

⦁ Use one of the previous equations to determine the density of the oil?

Expert Solution

V = volume of the object = Volume of the fluid displaced

= density of the object

= density of the oil

Fb = force of buoyancy acting in upward direction

Force of buoyancy is given as

Fb = V g

Fg = force of gravity acting in down direction

Force of gravity is given as

Fg = V g

Force equation for the motion of the object is given as

Fb - Fg = = ma

V g - V g = V a

g - g = a

a = ( - ) g/

a = ( / - 1) g

1)When the three blocks below are released from rest, they accelerate with a magnitude of 0.500m/s2. Block 1 has mass M, block 2 has 2M, and block 3 has 2M. What is the coefficient of kinetic friction 2)A block of mass m is held stationary on a ramp by the frictional force on it from the ramp. A force ?,directed up the ramp, is then applied to the block and gradually increased in magnitude from zero. During the increase, what...

Give the line numbers executed once power is applied, assuming the switch is released(it starts from the state: STATE_WAIT_FOR_PRESS) Keep writing numbers until you get a repeating pattern. It will start from line 11, which is the top of the while(1) loop Also describe what the LED does while the SW1 is repeatedly pressed and released. (specify the case when it blinks)

(a)Use Netwons Second Law of Motion to prove that the equation governing the forced damped harmonic oscillator (spring-mass system) is: mx"(t) + cx'(t) + kx(t) = F(t): (Explain what the constants m; c; k are and what the function F(t) is. Draw a picture of the system.) (b)Assume m = 1; c = 0; k = 4; that F(t) = cos(2t); and that the object attached to the spring begins from the rest position. Find the position function using the...
