Answer 2

Answer:

t=5s & S=25m

Explanation:

according to 1st equation of motion

v=u+at

on putting v=10,u =0 & a=2

& supposing t as x

10=0+2(x)

10=2(x)

x=10÷2

x=5

Now,from 2nd equation of motion

S=ut+1/2at^2

on putting u=0,a=2,t=5

& supposing S as y

y=0(5)+1/2(2)×(5)^2

y=1/2(2)(5)^2

y=1(5)^2

y=1(25)

y=25

S=25m & t=5s
