A bullet is fired with a speed of 720 m/s. a. What time is required for the bullet to strike a target at a position +324 m?

b. What is the velocity in km/h?

0.9s

2592km/hr

Explanation:

Given parameters:

Final velocity of the bullet  = 720m/s

Distance covered  = 324m

Unknown:

Time for the bullet to strike a target = ?

Velocity in km/h

Solution:

To solve this problem, we use the kinematics equation shown below:

     S  =( ) t

So;

        324  =  t

        324  = 360t

           t  = 0.9s

B. to convert this velocity to km/hr

       1000m  = 1km

       3600s  = 1hr

  720 x m x  x  x    = 2592km/hr
