Homework Statement
Evaluate the distance the cart travels from 18.0s to 21.0s.
The points are roughly (18.0, 22) and (21.0, 10). The slope/acceleration is constant.
Homework Equations
Δx=(v2f−v2i)/2a
Δx=0.5at2
Δx=0.5(base)(height)
The Attempt at a Solution
I used the first equation as:
Δx=(v2f−v2i)[itex]\overline{}2a[/itex]
=(222−102)/2(-4) = -48 m
Δx=0.5at2 = 0.5(-4)(9) = -18 m
Both of those were wrong along with the last equation (which also equaled -18 m). I really need help!
