Answer:
Explanation:
Thrust is known as a reaction force which appears when a system expels or accelerates mass in one specific direction. If we know the acceleration and the mass of the air expelled by the jet engine, we can compute the thrust
.
The acceleration is calculated by using the dynamics formula
The values are
The thrust is
At the end of one full time period, the ant has returned to where it was at the beginning of the time period. Its displacement is <em>zero</em>.
It will be unstable system because it will not be able to recover from the disturbance
Period = (1) / (frequency)
Period = (1) / (200 per second) = 0.005 second = 5 milliseconds
Answer:
194,400 joules of kinetic energy.
Explanation:
Remember that to calculate the Kinetic energy you need to use the next formula:
We know that Mass= 1200 kg and velocity is 18m/s, so we insert those values into the formula:
So the kinetic energy of a car moving at 18m/s with a mass of 1200 kg would be 194,400 joules.
