The Equation Below Is the Solution to a Physics Problem

question 13

Multiple Choice

The equation below is the solution to a physics problem: $\frac{1}{2}(2.30 \mathrm{~kg}) \left(3.90 \frac{\mathrm{~m}}{\mathrm{~s}}\right) ^{2}=\frac{1}{2}(2.30 \mathrm{~kg}) \left(2.33 \frac{\mathrm{~m}}{\mathrm{~s}}\right) ^{2}+(2.30 \mathrm{~kg}) \left(9.80 \frac{\mathrm{~m}}{\mathrm{~s}^{2}}\right) (1.00 \mathrm{~m}) \cos \left(60^{\circ}\right)$ .The most likely physical situation it describes is:

• A)a 2.30 kg cart rolling up a 30\(\degree\) incline.
• B)a 2.30 kg cart rolling down a 30\(\degree\) incline.
• C)a 2.30 kg cart rolling up a 60\(\degree\) incline.
• D)a 2.30 kg cart rolling down a 60\(\degree\) incline.
• E)a 2.30 kg cart rolling down a 90\(\degree\) incline.
