Answer:
(1) V = 0.2 J (2) 0.05J
Explanation:
Solution
Given that:
K = 160 N/m
x = 0.05 m
Now,
(1) we solve for the initial potential energy stored
Thus,
V = 1/2 kx² = 0.5 * 160 * (0.05)²
Therefore V = 0.2 J
(2)Now, we solve for how much of the internal energy is produced as the toy springs up to its maximum height.
By using the energy conversion, we have the following
ΔV = mgh
=(0.1/9.8) * 9.8 * 1.5 = 0.15J
The internal energy = 0.2 -0.15
=0.05J

Convert mL to gallons as follows:
355 mL = 0.355 L
0.355 L * (1 gal/3.785 L) = 0.0938 gallons
The equivalent km covered would be
57miles/gal * 0.0938 gal * (1.61 km/ 1 mile) = 8.61 kilometers
I hope I was able to help you. Have a good day!
Answer:
<h2>760 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 95 × 8
We have the final answer as
<h3>760 N</h3>
Hope this helps you
