Answer:
386 m
Explanation:
Let's call the horizontal distance between the point of launch and the point of landing of the first package 
.
2 seconds after landing at 
, the plane has travelled a horizontal distance of 
.
At this new point, the second package is launched. Because it is launched under the same conditions as the first, its horizontal distance from its point of launch is also 
.
To determine , we determine the time of fall of the package. Being a vertical motion, the drop has an initial velocity, 
, of 0 m/s with acceleration, 
, and a distance, 
, of 160 m. We use the equation of motion:
In this time, the package, with a horizontal velocity of 50 m/s, travels the horizontal distance, , of
The distance apart between both packages is

The force acting on the ball are unbalanced. Reactionary momentum force (that originated as a result of the swing of the bat) is the most powerful.
Yes friction is acting on the ball. In course of journey it would slow the ball down and make it trace a parabolic path rather than straight path as intended by hitter.
Explanation:
As the hitter hits the ball, momentum of the bat due to swing (mass of the bat*velocity provided by the batsman swinging action of bat) gets transferred on the ball on its impact with the bat.
Since ball’s mass is quite small as compared to the bat, the velocity of the ball increases by the same factor by which the ball’s mass is lower than the bat’s mass. This velocity causes forward motion of the ball (of course in the direction of bat’s motion, here the batsman intends to send the ball straight away hence the ball would move straight).
Various forces on ball is-
- Reactionary momentum force -bat’s force (most powerful force)
- The frictional force of the air (opposing the motion of the ball through the air)
- Gravity force (pulling the ball down to the Earth)
As a combined effect of these force when all the force remains unbalanced, the ball moves away in the straight path under the impact of bats momentum which was most powerful of all.
Frictional force and Gravity force continue acting on the ball. While frictional forces decrease the ball velocity through the air, gravity force pulls it down thus deflecting its direction. Under the combined impact of declining bats momentum, friction force and gravity force, the ball traces a parabolic path (in accordance with the first law of motion from Newton)
