Answer :
If a stuntwoman jumps from a height of 98.5 m into an airbag below, then she would have been falling with a velocity of 43.93 m /s on impact with the airbag had air resistance been absent.
What are the three equations of motion?
There are three equations of motion given by Newton,
v = u + at
S = ut + 1/2×a×t²
v² - u² = 2×a×s
As given in the problem if a stuntwoman jumps from a height of 98.5 m into an airbag below. If she struck the airbag at a speed of 40 m/s including the effects of air resistance,
By using the third equation of the motion,
v² - u² = 2 × a × s
v² - 0 = 2 × 9.8 × 98.5
v = 43.93 m /s
Thus, she would have been falling with a velocity of 43.93 m /s on impact with the airbag had air resistance been absent.
