Cars a and b travel along the same straight track. car a is located at position s1 at clock reading t1 and it maintains a constant speed of v1. car b is located at position s2 < s1 at clock reading t2, and it maintains a constant speed of v2 > v1. find an expression for the clock reading at which car b will overtake car a. find also an expression for the position at which car b overtakes car a. evaluate your expressions for the values s1 = 0.75 meters, t1 = 0.00 seconds, v1 = 0.38 m s−1 , s2 = 0.0 meters, t2 = 0.08 seconds, and v2 = 0.78 m s−1 .

a)

b)

c) t = 2.031s      X = 1.52m

Explanation:

Let X1 be position of car A as a function of time and X2 be the position of car B as a function of time:

X1 = Xo1 + V1*t     If we evaluate this expression at t=t1

S1 = Xo1 + V1*t1    Solving for Xo1 we get its initial position at t=0:

Xo1 = S1 - V1*t1    

Similarly for car B:

Xo2 = S2 - V2*t2

Now, to find the instant when car B overtakes car A:

X1 = X2   Replacing their functions in time:

(S1 - V1*t1) + V1*t  = (S2 - V2*t2) + V2*t   Solving for t:

  This is the instant when B reaches A

If we replace this expression in either X1 or X2 expression, we get that position:  X1 = X2

If we evaluate these two expressions with the given values:

t = 2.031s  and   X = 1.52m

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
