A small ball made of Styrofoam packing material is dropped from a height of $$3.0$$ m above the ground. Until it reaches terminal speed, the magnitude of its acceleration is given by a $$=$$ $$g-bv$$. After falling through $$1.0$$ m, the ball effectively reaches terminal speed and then takes $$4.0$$ more seconds to reach the ground. The value of the constant b is (take$$ g $$=$$ $$10$$ $$m/s2)

Question

Infinity Learn · Accepted Answer

when terminal speed is achieved $$a=0$$  $$g=bv$$ $$v=$$ $$g/b$$ $$s=vt$$ $$2=(g/b)$$ $$x4$$ b $$=2g$$ $$=20$$
