Answer: 11
Step-by-step explanation:
Since the smaller triangle is half of the larger triangle
5.5×2=11
In physics, work is equal to the product of force and distance, given that the direction of force is the same with the direction of the distance.
W = Fd
The total force is
F = 1,700 N + 500 N = 2,200 N
Now, if the question is the work needed to lift the barbell from the ground, the distance would be 2 m. Hence, the work would be
W = (2,220 N)(2 m) = 4,400 N·m or 4,400 J
Answer:
D
Step-by-step explanation:
The letter D includes a curved line, unlike the letters X, M, and F.
