A body of mass 5 kg starts from the origin with an initial velocity $\stackrel{\to }{u\text{\hspace{0.17em}}}\text{\hspace{0.17em}}=\text{\hspace{0.17em}}30\stackrel{^}{i}+40\stackrel{^}{j}\text{\hspace{0.17em}}m{s}^{-1}$. If a constant force $\stackrel{\to }{F\text{\hspace{0.17em}}}=-\left(\stackrel{^}{i}+5\stackrel{^}{j}\right)N$ acts on the body, the time in which the y–component of the velocity becomes zero is

(1) 5 seconds

(2) 20 seconds

(3) 40 seconds

(4) 80 seconds
