Question

two car p and Q start from a point at the same time in a straight line and their positions are represented by ​

Answer 1

Answer:

d) is correct answer

Explanation:

function of position is given

differentiate both the expression wrt time to obtain expression for their velocities

V1= a + 2bt

V2 = f-2t

let at time t both cars have same velocity

a+2bt = f-2t

a-f= t(-2-2b)

t= (f-a)/2+2b
