Question

a girl accelerate s at a rate of 18km/h to 45km/h in 5sec. calculate its acceleration and distance covered​

Answer 1

Answer:

formula is :

1. a = v-u/t

in which a = acceleration

u = initial velocity

v = final velocity

t = time of journey So, a = 45-18/5= 41.4m/s sq.

2. s = 1/2(u+v )t

s = 1/2(18+45)5

s= 157.5m

I HOPE THIS WILL HELP U...

PLEASE MARK ME AS BRAINLIST, THANKS...☺
