W = F × s
W = 15kN × 40 m
W = 15.000 N × 40 m
W = 600.000 J
P = W/t
P = 600.000 J/2 s
P = 300.000 Watt
P = 300kWatt

Answer: 0.169 (3 s.f.)
Explanation:
Force = 76 N
Spring constant = 450 N/m
Extension/displacement = x
Hooke's law states that: F = kx
Therefore, 76 = 450 X x
76/450 = x
0.169 (3 s.f.) = x
