2. I shoot a bullet up with a speed of 432km/hr in 1.5 seconds. If free fall acceleration
is 9.8m/s" Find: initial velocity: acceleration of ball going up, acceleration of ball falling
down: initial velocity of ball falling down; velocity of ball falling down; times takes for
ball to fall down time take for bal to fall down

Answer:
given = speed = 432 Km/hr
time = 1.5sec
accelaration = 9.8m/s
to find = initial velocity
solution =
use the equation = V = u + at
object is freely falling .....(given )so ,initial velocity is 0.
V = U + at
V = 0 + 9.8 + 2.5
V = 19.6m/s
accelaration of object is due to earths gravity it is 98 so,downwards accelaration is 19.6m/s
