Join us for a dramatic river rescue mission! In this video, we solve the problem of how a rescue team can reach a child in danger of drowning in a fast-flowing river. We calculate the angle from the shore for their pilot to approach the child directly, considering the river's current and the boat's speed. Explore the principles of vector addition and save lives!
Projectile Motion: Speed, Height, Time & Range
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Join us for an engaging exploration of projectile motion as we dissect a fascinating scenario. We delve into the physics of a projectile fired with an initial speed of 36.6 m/s at an angle of 42.2° above the horizontal on a flat firing range. Discover how to determine the maximum height, total time in the air, total horizontal distance covered (range), and the speed of the projectile 1.50 seconds after firing. This video will demystify the dynamics of projectiles in a clear and educational manne
