In figure 2 show below, the body reaches a velocity of 12 m/ sec during traveling 30 m starting from rest moving with constant acceleration. Find the coefficient of friction between the body and ground? P =300 N , W = 200 N
This most likely is made to be a probelm about mx''+bx'+kx=f(t)
m = mass
b = friction
k = spring constant
4. A mass weighing four pounds stretches a spring 24 in. Suppose the mass is atequilibrium and is set into motion with a velocity of 6 inches per second. The mass is in a mediumwhere friction is small, and we assume it is zero. Note that the acceleration due to gravity near theearth’s surface where the experiment takes place can be taken as 32 ft/s2.(a) Suppose that in addition to the conditions described above, a hammer strikes the mass everyπ/2 seconds starting at t = 0. A delta function with impulse of 1 pound-second models theforce of each blow to the mass. Find the function x(t) for the displacement from equilibrium infeet of the mass at time t in seconds. Express x(t) as a piecewise defined function without the use ofunit step or Heaviside functions and such that in each time window it is a different multiple of the samesinusoidal function.(b) Now assume the same spring-mass…
A disk rotating with constant acceleration of 0.005 revolutions / s2
And the movement starts from rest. What is the angle velocity after one minute? How many turns makes the same disc in point number one after one minute. If an external force does not affect the body, what does that mean? And if the body is in free fall, is its speed constant or variable, what is its acceleration equal, and how can the friction be reduced between the contact surfaces
