Answer:
5 J
Explanation:
F = spring force required to stretch the spring = 10 N
x = stretch in the spring = 1 m
k = spring constant of the spring
Spring force is given as
F = k x
Inserting the values
10 = k (1)
k = 10 N/m
W = work done in stretching the spring
Work done is given as
W = (0.5)k x²
Inserting the values
W = (0.5) (10) (1)²
W = 5 J
