━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Given,

• $\small \underline {\sf{ u=0}}$

• $\small \underline {\sf{ a=5m/s ^2}}$

• $\small \underline {\sf{t=5sec }}$

Using newton's first equaion of motion :

$\small \underline {\sf{v=u+at }}$

$\small \underline {\sf{V=0+5x5 }}$

$\small \underline {\sf{ a=5m/s ^2}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Answer 2

Answer:

u=0

a=5m/s^2

t=5sec

Using Newton's first eqn of motion

V=u+at

A=5m/s^2
