If a mass weighing 56 lbs stretches a spring 6 inches what is the spring constant? if the mass has a velocity of 4 ft/sec and this results in a viscous resistance of 40 lbs what is the damping coefficient? assume 32 lb = 1 slug 32lb=1 slug

i will answer your question if you answer mine

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

just took the test its not "d"
