Answer:
7.5m/s
Explanation:
v=0
t=1.5s
a=-5m/s²
v=u+at
u=v-at = 0-(-5)1.5 =7.5m/s

answer: initial velocity= 7.5m/s
explanation:
here ,
retardation= 5m/s^2= -5 m/s^2
time = 1.5 sec
we have , v= u+at
here final velocity v = 0 ( rest )
initial velocity u = ?
acceleration= retardation= 5m/s^2
=> 0= u+ (-5)(1.5)
=> u= 7.5m/s
