Question

Along horizontal direction:

vo = velocity of each package = 3.3 m/s

a = acceleration = 0 m/s2 (since there is no force along the x-direction)

t = time taken between the two packages = 5 sec

x = distance between the two packages

Using the kinematics equation

x = vo t + (0.5) a t2

x = (3.3) (5) + (0.5) (0) (5)2

x = 16.5 m

Along vertical direction :

vo = velocity of each package = 0 m/s

a = acceleration = 9.8 m/s2

t = time taken by each package

y = vertical height traveled by each package = 100 m

Using the kinematics equation

y = vo t + (0.5) a t2

100 = (0) t + (0.5) (9.8) t2

t = 4.5 sec
