Answer:
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. ... For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.
Answer:
-60.82 m/s²
Explanation:
recall that the acceleration due to gravity, g = 9.81 m/s²
We must also realize that during the car crash, the moving car is being brought to a stop. Hence, it is actually a deceleration (i.e a negative acceleration)
Therefore we must add a negative sign to our acceleration to describe the deceleration.
acceleration = - 6.2g
= -6.2 x 9.81 m/s²
= -60.8 m/s²
