When the mass of 2.0 kg is attached to the spring, the force applied to the spring is the weight of the mass, so
This force stretches the spring by
, so we can use Hook's law to find the spring constant:
Then the mass of 2.0 kg is removed and replaced with another mass m2=2.7 kg. The force produced by this mass is equal to its weight:
And so, we can use again Hook's law to calculate the new stretch of the spring:
The ball that is thrown into the air with a velocity of 44 ft/s, its height in feet t seconds later is given by the following equation:
y=46 ft/s * t - (32.17 ft/s² * t²/2)
The height in (ft) at a time (t) of a body that has been thrown with a certain velocity and is in vertical motion is given by the following equation:
y = vi * t - (g* t²/2)
Where:
- y = height
- vi = initial velocity
- g = gravity
- t = time
Information about the problem:
- vi = 46 ft/s
- g = 32.17 ft/s²
- y =?
- t = t
Applying the height formula we get:
y = vi * t - (g* t²/2)
y = 46 ft/s * t - (32.17 ft/s² * t²/2)
<h3>What is the vertical upward launch?</h3>
It is the movement described by an object that has been thrown vertically upwards in which the height and the effect of the force of the earth's gravity on the thrown object are considered.

Answer:
California has one of the most variable climates of any U.S state, and often experiences very wet years followed by extremely dry ones . The state's reservoirs have insufficient capacity to balance the water supply between wet and dry years
