<em>pf = 3750000 kg.m/s</em>
<em>F = 175000 N</em>
Explanation:
<u>Constant Acceleration</u>
An object moves with constant acceleration if its velocity changes uniformly in time.
If we call vo to the initial speed, vf the final speed, and t the time, then the acceleration is calculated as:
The new stealth helicopter was traveling at vo=180m/s and changed to vf=250 m/s in t=6 seconds, thus the acceleration was:
<em>Please note this number is shown rounded to the nearest hundredth, but it was stored in the calculator's memory with full precision. This fact affects the next calculation as will be noted below.</em>
The acceleration must be produced for some net force that can be calculated by:
F = m.a
Where m=15000 Kg is the mass of the helicopter. Thus:
F = 15000 * 11.67
F = 175000 N
<em>The above product would lead to the inaccurate result of 175050 if the acceleration would have not used with its full representation in the calculator's memory.</em>
The momentum of an object of mass m and velocity v is:
p = m. v
The final momentum of the helicopter is:
pf = m.vf = 15000*250 m/s
pf = 3750000 kg.m/s
<u>Note: When performing calculations over intermediate results, it's important to keep them as accurate as possible to preserve the accuracy of the final result.</u>
Answer:
Option C
80 years
Explanation:
<em>From Scientific records, the rate of movement of the plate is 0.025 meters</em>
Since the fault moves at the rate of 2 meters per year, to obtain the number of years it will takes to produce an earth quake, we will have to divide the rate of movement of the fault by the rate of movement of the plate.
Number of years for earthquake = = 80 years.
Hence, it will take 80 years to produce one big earthquake.
