Asmall piece of styrofoam packing material is dropped from a height of 1.90 m above the ground. until it reaches terminal speed, the magnitude of its acceleration is given by a = g β bv. after falling 0.400 m, the styrofoam effectively reaches terminal speed, and then takes 5.40 s more to reach the ground.(a) what is the value of the constant b? s-1(b) what is the acceleration at t = 0? m/s2 (down)(c) what is the acceleration when the speed is 0.150 m/s? m/s2 (down)
