Answer:
21N
Step-by-step explanation:
M. A = WORK OUTPUT ÷ WORK INPUT
Where M. A = 3.5 AND WORK OUTPUT = 75N
WORK INPUT = WORK(FORCE) OUTPUT ÷ M. A
= 75 ÷ 3.5 = 21.428
THEREFORE FORCE THE NUTCRACKER APPLIES TO THE WALNUT = 21.428 = Approx as 21N
Given: 75N force on nutcracker, 3.5 force on walnut
Using formula M. A = WORK OUTPUT ÷ WORK INPUT where M. A is not given W. O = 75N and W. I = 3.5N
75÷ 3.5 = 21N
