Yes u can help I need to see th worksheet to help tho
Answer:

Explanation:
given,
s = 400- 16 t²
we know,
Velocity of an object is defined as the change in displacement per unit change in time.
velocity an also be return as




Hence, instantaneous velocity function given by 
To calculate instantaneous velocity, you need to insert value of time.
ex, instantaneous velocity at t = 4 s
v = -32 x 4 = -128 m/s.
These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a golgi apparatus that packages and distributes proteins.
Answer:
Due to the fact that the comb is in terms of mass bigger than pieces of paper
Explanation:
In terms of mass, the comb is way too bigger than the piece of paper so it is virtually impossible for it to move towards the pieces of paper
According to Newton third law action and reaction are equal and opposite
Mathematically
P=m*v
Where
P= impulse is Newton
m=mass of the body
V= velocity of the body
Now since the comb has a greater mass it will not move to the paper, else the paper must have to move to it.
