Answer:
18000 J
Explanation:
From the question given above, the following data were obtained:
At point 4:
Mass of cart = 600 Kg
Velocity of cart (v) = 7.745 m/s
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 600 × 7.745²
KE = 300 × 7.745²
KE ≈ 18000 J
Therefore, the mechanical energy of the cart at point 4 is 18000 J

<h3>step 1. start with what is at the top of the list.</h3>
<h3>step 2. do 1 times 3 since it comes before division, and is in parentheses.</h3>
1 × 3 = 3
<h3>step 3. find 36 divided by 2</h3>
36 ÷ 2 = 18
<h3>step 4. add the values together</h3>
18 + 3 = 21
<h3>step 5. find 14 times 3</h3>
14 × 3 = 42 <em>you can also do 7 × 6 and will get the same result because 7 is half of 14 and 3 is half of 6</em>
<h3>step 6. add what is outside the parentheses</h3>
21 + 42 = 63
<h3>step 7. divide by 6</h3>
63 ÷ 6 = 10.5
10 remainder of 3 <em>remainder means left over</em>
