Answer:
19372.29 N
Explanation:
Kinetic Energy of the man = Work done by the average resistive force of water.
mg(H+d) = F×d............................ Equation 1
where, m = mass of the woman, H = Height of the platform, d = depth of water reached, F = average resistive force exerted by water.
make F the subject of the equation,
F = mg(H+d)/d...................... Equation 2
Given: m = 65.0 kg, H = 10 m, d = 3.4 m, g = 9.8 m/s²
Substitute into equation 2
F = 65(9.8)(100+3.4)/3.4
F = 19372.29 N
