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
Answer:
3 is the GCF for all these numbers if thats what you're asking
Answer:

Answer:
1.25 s
Explanation:
We are given that
Initial velocity of boy=u=0
Time=0.883 s
Let x be the total distance covered by boy in entire trip.
s=
We know that
Where 
Substitute the values
m
Again using the above formula
Hence, 1.25 s passes during his entire tripe from the top down to the water.
0.1 m/s^2 (final velocity-initial velocity) and then divide with the time taken
