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 ag - 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 = 07
m/s² (down)
(c) What is the acceleration when the speed is 0.150 m/s?
m/s2 (down)
