+
+ <h3>Solution</h3>
+ <p>
+
+<p>For a body to fly along a parabola, it is necessary that at the moment of separation it be in a state of weightlessness</p>
+<p>The force of gravity will be compensated by centrifugal force</p>
+<p class="exp">
+$$ mg = \frac{mv^2}{r} $$
+</p>
+<p>Where do we express $v$</p>
+<p class="exp">
+$$\boxed{v = \sqrt{gr}}$$
+</p>
+ </p>
+
+ <h4>Answer</h4>
+ <p>
+ $$v = \sqrt{gr}$$
