MY NOTES PRACTICE ANOTHER A small piece of Styrofoam packing material is dropped from a height of 2.60 m above the ground. Until it reaches terminal speed, the magnitude of its acceleration is given by a = g- 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? ASK YOUR TEACHER (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) Need Help? Read It Watch
