C. is the answer. You can't use plastic because it does not conduct electricity and string does not conduct electricity either so the circuit will end before it get to the bulb.
The answer is directed northward. The acceleration will be negative, since the car is decelerating. Thus the power that is slowing it down must be performing in the opposite direction to that which the car is traveling. Or in other words, when speed is lessening, acceleration is in the opposed direction to velocity. The change is CONTRASTING the velocity and so it slows it down.
Answer:
8 m/s² south
Explanation:
Given:
v₀ = 40 m/s
v = 0 m/s
Δx = 100 m
Find: a
v² = v₀² + 2a (x − x₀)
0² = 40² + 2a (100)
a = -8
The acceleration is 8 m/s² south.
Answer:
Take the numbers and fill them in graph.
Plot time as X and speed as Y and afterward join then like a line graph.
