A small, spherical underwater organism has a radius ro and is moving at a speed of vo. The organism experiences a viscous force and a drag force from the water. If the radius of the organism decreases to r0/4 and its speed increases to 2v0, Required:
What will be the viscous and drag forces on the organis?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

force tends to be low and long diustance masses are high
