Answer:
a= 2.667 m/s²
Explanation:
Given that
Initial velocity ,u= 2 m/s
Final velocity ,v= 10 m/s
Time taken ,t= 3 s
As we know that
v = u + at
a=Acceleration ,u=Initial velocity ,v= Final velocity ,t=time
Now by putting the values in the above equation
v = u + at
10 = 2 + a x 3
8 = 3 a

a= 2.667 m/s²
Therefore the acceleration of the biker will be 2.667 m/s²

So, according to the question:
distance = 90 miles
time = 1h 45min + 15 min + 1h = 3h

Answer:
a)

Answer:
it is due to anamolous expansion of water as water cools from 4dg.c to 0dg.c. it expand making ice lighter than water to float
