Answer:
a = 20.5931 g,
D = 488.88 meters
Explanation:
We can find acceleration using the formula
V = Vo + a*t, where V is the final speed, Vo is the inicial speed, a is the acceleration and t is time.
First, we need to convert the speed to meter/seconds:
V = 1600 km/h = 1600/3.6 m/s = 444.44 m/s
Then, using Vo = 0 (starts from rest), we have:
444.44 = 0 + a*2.2
a = 444,44/2.2 = 202.0182 m/s2
In terms of g (g=9,81 m/s2), we have that:
a = 202.0182/9.81 g = 20.5931 g
To find the distance travelled, we can use Torricelli's equation:
V^2 = Vo^2 + 2*a*D, where D is the distance travelled. So:
444.44^2 = 0^2 + 2*202.0182*D
D = 197526.91/404.0364 = 488.88 meters
