The relation b/w time t and distance x is t = ax.sq + bx . where a & b are constants . the retardation is given by :
a) 2a(v).cube
b) 2b(v).cube
c) 2ab(v).cube
d 2(bv).cube
Please explain ??

Expert Answer
Option 1 is true. You must just differentiate the given equation t = ax.sq + bx twice, with respect to t and then substitute the value of 2ax+b as equal to 1/v (this can be get from the first diffentiation of the given equation)
