Answer
Speed depends on the amount of force you put into it... it the force is the same on the each surface then it will depend on the roughness of the surface as in friction
Use photo math for that 21
Answer:
vertical asymptote at x=-1
horizontal asymptote at y=0
Step-by-step explanation:

To find vertical asymptote we set the denominator =0 and solve for x
x+1=0 (subtract 1 from both sides)
x=-1
So, vertical asymptote at x=-1
To find horizontal asymptote we look at the degree of both numerator and denominator
there is no variable at the numerator , so degree of numerator =0
degree of denominator =1
When the degree of numerator is less than the degree of denominator
then horizontal asymptote at y=0
