Question

A body is moving according to the equation
x = at +bt2 - ct3 where x = displacement and a,
b and c are constants. The acceleration of the
body is
a) a + 2bt
b) 2b +6ct
c) 26 – 6et
d) 36-6ct²​

Answer 1

Answer:

its third option is correct

Answer 2

(B)2b+6ct

a= dv/dt=d²x/dt²= d²(at+bt²-ct³)/dt²

a= 2b+6ct
