Both balls hit the ground at the same time.
We've known this fact for about 500 years (since Galileo),
and we've known WHY for about 300 years (since Newton).
In order to convert the ft^2 to m^2, we use the multiplier 0.09290304.
Therefore your calculation would be: 0.09290304 · 1930 = 179.303m^2 (rounded to 3 d.p)
Acceleration is the rate of change of the velocity of an object.
Explanation:
Let is the frequency of oscillation of a block that undergoes simple harmonic motion. The frequency of oscillation is given by :
...............(1)
Where
k is the spring constant of the spring
m is the mass of the block
It is clear from equation (1) that the frequency of the oscillation depends on the spring constant and the mass of the block. So, on increasing the spring constant, the block oscillate with a greater frequency.
