Question

u=? a=5 t=2 v=20 v=u+at​

Answer 1

ram ram ...

good evening...

a = 5m/s^2

t = 2s

v = 20 m/s

by 1 st equ. of motion..

u = v/at

= 20/10

u = 10 m/s..

hope it helps...

Answer 2

u=?

a=5

t=2

v=20

by using equation of motion we get...

v=u+at

20=u + 5 ×2

20=u+10

20- 10 =u

so u= 10 m/s....

hope it helps u..thank yuh...:-)❣
