The answer & explanation for this question is given in the attachment below.
In order to calculate the time taken by the snowball to reach the highest point in its journey, we need to consider the variables along the y-direction.
Let us list out what we know from the question so that we can decide on the equation to be used.
We know that Initial Y Velocity = 8.4 m/s
Acceleration in the Y direction = -9.8 m/
, since the acceleration due to gravity points in the downward direction.
Final Y Velocity = 0 because at the highest point in its path, an object comes to rest momentarily before falling down.
Time taken t = ?
From the list above, it is easy to see that the equation that best suits our purpose here is
Plugging in the numbers, we get 0 = 8.4 - (9.8)t
Solving for t, we get t = 0.857 s
Therefore, the snowball takes 0.86 seconds to reach its highest point.

Height of Aeroplane = 500 meters
Speed of Aeroplane = 200 m/s
Acceleration due to gravity = g = 10m/s^2
time of package to reach the ground = t = ?
Horizontal distance = d = ?
<h2>_____________________________________</h2><h3>SOLUTION:</h3>When the bomb is dropped, it will have an initial horizontal velocity which is equal to the speed of the plane as the plane is just moving in horizontal direction. So the bomb fall and will travel forward.
Initial horizontal velocity is given by,
Initial vertical velocity is given by,
By the second equation of motion under gravity,
<u>For horizontal distance(d)</u>:
Horizontal distance has no acceleration thus d is given by
d = vt
d = 200x10
d = 2000 meters
