Answer:
c. 40200 J
Explanation:
Assume gravitational constant g = 9.8m/s2. The weight of the 2000kg vehicle is

In addition to the friction averaging at 500N, the total force is
F = 20000 + 500 = 20100 N
The work required to generate this force over a distance of 2m would be
F*s = 20500 * 2 = 40200 J
So c.40200 J is the correct answer
Answer:
160,000 N
Explanation:
Given:
m = 320,000 kg
v₀ = 0 m/s
a = constant
t = 57 s
Δx = 810 m
Find: Fnet
Apply Newton's second law:
∑F = ma
Fnet = ma
To find Fnet, we must first find the acceleration.
x = x₀ + v₀ t + ½ at²
810 m = 0 m + (0 m/s) (57 s) + ½ a (57 s)²
a = 0.50 m/s²
Fnet = (320,000 kg) (0.50 m/s²)
Fnet = 160,000 N
Answer:
The statement that offers a hypothesis on how people’s backgrounds and interests influence their work is that a person’s background and interests can give him a unique perspective in his research. The correct option is B.
Explanation: Alot of scientist has contributed one way or the other in the model of atoms and this was soo because of their background and interests which gave them a unique perspective in the study of the model of atoms. For example John Dalton who was known to propose the atomic theory, studied chemistry( he had a strong background in knowledge of chemistry) and he had interest in the study of the physical properties of the atmosphere and other gases. This gave him a unique perspective in his research works.
