Need physics help. (dealing with original speed and acceleration)?
A truck covers 42.8 m in 8 s while smoothly slowing down to a final speed of 3.2 m/s.
What its original speed in units of m/s?
What its acceleration in units of m/s2?
You can use the equations
v = u + at
v^2 = u^2 +2ad
d = ut + (1/2)at^2
d = (1/2)(u + v) x t
v = final velocity (3.2m/s)
u = intial velocity (unknown)
a = acceleration (unknown)
t = time ( 8s )
d = distance (42.8m)
First we'll use d = (1/2)(u + v) x t
42.8 = (1/2)(3.2 + u) x 8
42.8 = 4(u + 3.2)
42.8/4 = u + 3.2
10.7 = u + 3.2
10.7 - 3.2 = u
u = 7.5m/s
Which is the initial speed.
Now we can put this into the first equation.
v = u + at
3.2 = 7.5 + 8a
-4.3 = 8a
-0.5375 = a
Acceleration is -0.5375ms^-2
So your answers are.
1) 7.5m/s
2)-0.5375ms^-2
Hope this helps =)
