Question

In a classroom demonstration, a glider moves along an inclined air track with constant acceleration a. It is projected from the start of the track (x = 0 ) with an initial velocity Vo. At time t = 8s, it is at x =100 cm and is moving along the track at velocity v = -15 cm/s. Find the initial speed Vo and acceleration a.

Answer 1

Hello, what is the first step?

Answer 2

v (final) = v (initial) + a x t

You are looking for initial.

Answer 3

Thats your formula. Do you know how to set it up?

Answer 4

-15 = Vo + a (8)

Answer 5

How can I use this formula I've two variables :/

Answer 6

Let me get you help :)
@missMob Can you help her out? Im still rusty /.\

Answer 7

okay lemme see
