Help me guyz

A shell of mass m is fired from a gun carriage of mass M which is initially at rest but free to roll on a frictionless level track. The muzzle speed of shell is v relative to the gun ,maximum range of shell if gun is inclined at an angle $\alpha$ to horizontal

A hammer of mass M falls from a height h repeatedly to drive a pile of mass m into the ground . The hammer makes the pile penetrate into the ground to a distance d in a single blow. Opposition to penetration is given by

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
