Question

solve pls faster
plsss​

Answer 1

Initial velocity=?

final velocity=0

time=10

accelaration=-2.5m/s2

a = v-u/t

a = v-u/t-2.5 = 0-u/10

a = v-u/t-2.5 = 0-u/10-2.5 = -u/10

a = v-u/t-2.5 = 0-u/10-2.5 = -u/10-2.5*10 = -u

a = v-u/t-2.5 = 0-u/10-2.5 = -u/10-2.5*10 = -u-25 = -u

a = v-u/t-2.5 = 0-u/10-2.5 = -u/10-2.5*10 = -u-25 = -u25=u

THUS ,

the answer is 25 m/s.

THANK YOU ✌️

HOPE IT HELPS YOU ⭐

Answer 2

Answer:

v =0

u = ?

a = -2.5m/s²

t = 10s

we know that,

v=u+at

0=u + (-25)

-u = -25

u = 25 m/s
