Answer:

\Delta E=100

Explanation:

To find the potential difference between x_{i}=2.0m and x_{f}=3.0m, we just need to observe which vertical coordinates belong to these given values.

From the graph, we observe that x_{i}=2.0m correspond to E_{i}=100, because they form the point (2,100) which is given in the graph.

With the same reasoning, we observe that E_{f}=200 corresponds to x_{f}=3.0m, because they both together form the points (3,200).

Now, the potential difference between the given distances, we just need to subtract

\Delta E=E_{f} -E_{i}=200-100=100

Which also refers to the variation of the potential.

Therefore, the potential differential is \Delta E=100

From the graph given, the y-axis represents the potential energy while the x axis is represents the displacement. To calculate the potential difference, I think the values from point two to point one should be only subtracted.

Potential difference = 200 - 100 = 100 V/m

a 1500 kg car traveling at 15 m/s to the south collides with a 4500 kg truck that is intially at rest at a spotlight. The car an
harkovskaia [24]

Answer:

3.75 m/s south

Explanation:

Momentum before collision = momentum after collision

m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂

Since the car and truck stick together, v₁ = v₂.

m₁ u₁ + m₂ u₂ = (m₁ + m₂) v

Given m₁ = 1500 kg, u₁ = -15 m/s, m₂ = 4500 kg, and u₂ = 0 m/s:

(1500 kg) (-15 m/s) + (4500 kg) (0 m/s) = (1500 kg + 4500 kg) v

-22500 kg m/s = 6000 kg v

v = -3.75 m/s

The final velocity is 3.75 m/s to the south.
