(a) The average force experienced by the person for 0.85 cm compression is 3,722,425.8 N.
(b) The average force experienced by the person for 13 cm compression is 243,389.4 N.
Kinetic energy of the person
The kinetic energy of the person is calculated as follows;
K.E = ¹/₂mv²
K.E = ¹/₂ x 62.5 x 22.5²
K.E = 15,820.31 J
(a) Average force experienced by the person for 0.85 cm compression
E = ¹/₂Fx
2E = Fx
F = (2E)/x
F = (2 x 15,820.31)/(0.0085)
F = 3,722,425.8 N
(b) Average force experienced by the person for 13 cm compression
F = (2 x 15,820.31)/(0.13)
F = 243,389.4 N
