Answer:
2) 2m/s² is the answer
explanation!
as the particle is moving towards north (i.e. in opposite direction of gravity) it is negative acceration or retardation.
u(intial velocity) = -5m/s
v (final velocity) =5m/s
t =5 second
acceration (a) = rate of change of velocity
=v-u/t
=5-(-5)/5
=10/5
= 2 m/s²
