Here are the equations you need:
vertical acceleration of the ball = -9.8
Which is constant. All the while, the answer to Part C
=- 9.8t + V0 vertical speed.
V0 know, is 1000 m / s
The vertical displacement of the drawer = -4.9 (t ^ 2) + V0T
The bullet reaches its maximum height, while its speed = 0 To solve the rate equation for the velocity v = 0
Once you have this t connect it to the displacement equation to determine the murderer dispalcement the ball at the top.
The speed in the climb to draw a straight line of slope -9.8. The average is currently at half the current levels, ie 500 m / s to 500 m / s on the way down.
The average speed was 500 m / s

Need more information to the answers you want.
Type of weapon, bullet type grain ball speed and wind direction, the final velocity) of the ball (on the basis of mass, the time of the year (air temperature play a role). .. etc.
