Answer:
V = (-32t +32) ft/s
The velocity of the bowling ball after t seconds is the time derivative of the position function s(t). To obtain the velocity from s(t) we simply differentiate s(t) with respect to t. That is
V = ds(t)/dt = -16×2t + 32×1 = -32t + 32.
When differentiating, you multiply the coefficient of each term in the equation with the power of the variable and then reduce the power by 1 just like above.

Explanation:
Allison can measure the mass of the rock by using a scale. An electronic beam balance will be able to give her the mass of the rock to a fairly accurate degree.
To go about measuring the volume of the rock, an indirect approach has to be adopted since the rock is not regular in shape. Allison would have to adopt a principle that explains that the volume a solid body displaces when immersed in a pool of liquid, is directly equal to the volume of the solid itself.
This means that if the stone is placed in a beaker of water containing an already measured volume of water, the increase in the volume of the water when the stone is immersed is equivalent to the volume of the stone.
Answer:
Solar flare
Explanation:
In the Sun when there is an sudden increase in brightness which is generally accompanied by a coronal mass ejection it is known as a solar flare. Solar flares occur close to Sun spot.
Coronal mass ejection is the release of matter (plasma) with a strong magnetic field from the corona of the Sun.
The energy they release ranges between 
which is comparable to 100-megaton hydrogen bombs exploding simultaneously

Explanation:
Answer:
The height of the cliff is 90.60 meters.
Explanation:
It is given that,
Initial horizontal speed of the stone, u = 10 m/s
Initial vertical speed of the stone, u' = 0 (as there is no motion in vertical direction)
The time taken by the stone from the top of the cliff to the bottom to be 4.3 s, t = 4.3 s
Let h is the height of the cliff. Using the second equation of motion in vertical direction to find it. It is given by :
h = 90.60 meters
So, the height of the cliff is 90.60 meters. Hence, this is the required solution.
