Question

5. A bullet is fired at an angle of 15° with the horizontal and hits the ground 6 km away. Is it possible to hit a target 10 km away by adjusting the angle of projection assuming the initial speed to be
the same ?
​

Answer 1

Answer:

yes it is possible

hope it helps

Answer 2

Explanation:

Range R=u

2

Sin2θ/g=6000meter

so u

2

=120000m/s so u=346.4m/s

Note, we used Sin2θ=Sin30

0

=0.5

Now we know that the maximum value of range is given as R

max

=u

2

/g=120000/10=12000meter=12Km

So its possible to hit the target at 10Km distance because its less than maximum range.
