Answer:
d = 0.38 m
Explanation:
As we know that the person due to the airbag action, comes to a complete stop, in 36 msec or less, and during this time, is decelerated at a constant rate of 60 g, we can find the initial velocity (when airbag starts to work), as follows:
vf = v₀ -a*t
If vf = 0, we can solve for v₀:
v₀ = a*t = 60*9.8 m/s²*36*10⁻³s = 21.2 m/s
With the values of v₀, a and t, we can find Δx, applying any kinematic equation that relates all of some of these parameters with the displacement.
Just for simplicity, we can use the following equation:
where vf=0, v₀ =21.2 m/s and a= -588 m/s².
Solving for d:
⇒ d = 0.38 m
Answer : <u><em>Gravitational potential energy</em></u>
Explanation :
Gravitational potential is defined as the work done in moving an object from a fixed reference location to the location of object. This arises from the law of gravity and it acts against the gravity.
Mathematically, it is defined as potential energy (U) per unit mass (m).
i.e.
The general form of Gravitational energy is
where, is gravitational constant
and
are masses of interacting bodies
and is the distance between them.
Negative sign shows here that the system is bound.
