You used density, because water/ice has a density of 1, and ice will sink in anything with a lesser density
According to Newton's Second Law of Motion, the net force experienced by the system is equal to the mass of the system in question times the acceleration in motion. In this case, the net force is the difference of gravitational force and the force experience by the motion of the airplane. This difference is already given to be 210 N.
Net force = ma
210 N = (73 kg)(a)
a = +2.92 m/s²
Thus, the acceleration of the airplane's motion is 2.92 m/s² to the positive direction which is upwards.
Answer:
Mechanical Energy
Explanation:
The sum of kinetic energy and potential energy of an object is its total mechanical energy.
Oh my lord lol I was do ready to help then I saw numbers
Answer:
that one i know only pe not that sorry again
