<h2>
1.Kinetic energy =147000 joule</h2><h2>
2.Kinetic energy =25 units</h2><h2>
3.Kinetic energy =5 0 units</h2><h2>
4.Kinetic energy = 200 units</h2>
Step-by-step explanation:
1.
Kinetic energy =
Here m = 1500 kg and v = 14 meter / second
Kinetic energy = = joule =147000 joule
2.
Here m = 2 unit and v = 5 units
Kinetic energy = = units =25 units
3.
Here m= 2 units and v = 5 units
Kinetic energy = ==5 0 units
4.
Here m= 2 units and v= 10 units
Kinetic energy ==units = 200 units
<h3>Answer</h3>
False
<h3>Explanation</h3>
Here is a counterexample:
Let x = 3. Then
but
So these expressions are not equivalent
Answer:
x = 54
Step-by-step explanation:
These angles are complementary because they add up to 90:
x - 7 + 43 = 90
x + 36 = 90
x = 90 - 36
x = 54
