Question with many parts. please help! The spped at which a raindrop falls increases until a maximum speed, called its terminal velocity, is reached. The raindrop then continues to fall at this terminal velocity. The distance, s metres, it falls is given by s(t)=6t+0.3t^2-0.01t^3 when 010 where t is time iin seconds from the instant the raindrop begins to fall and k is a constant.

The spped at which a raindrop falls increases until a maximum speed, called its terminal velocity, is reached. The raindrop then continues to fall at this terminal velocity. 
The distance, s metres, it falls is given by

s(t)=6t+0.3t^2-0.01t^3 when 0<or= t <or=10
s(t)=k(t-10) t>10

where t is time iin seconds from the instant the raindrop begins to fall and k is a constant.

How far has this raindrop fallen after 10 seconds?

anonymous · Answer

After how many seconds is the rainidrop falling at a speed of 8.25 metres per second?

anonymous · Answer

The acceleration of the raindrop is decreasing for the first 10 seconds of its fall. Find the value of t for which the acceleration is 0.006ms^-2

anonymous · Answer

The raindrop falls vertically from a height of 620 metres. How long will it take the raindrop to fall to ground level?

anonymous · Answer

A raindrop increases in size as it falls. The volume of a spherical raindrop increases at  a rate of 6 cubic centimetres per scond. Findthe rate at which the radius of the raindrop is increasing when the radius is 1.5mm
