00:07:00 Horizontal Projectile Motion Introduction with animations
00:10:30 Example 4.8 (Explanations for Horizontal Projectile Motion) A hiker stands on the edge of a cliff 490 m above the ground and throws a stone horizontally with an initial speed of 15 m/s. Neglecting air resistance, find the time taken by the stone to reach the ground, and the speed with which it hits the ground. (Take g = 9.8 m/s^2)
00:25:40 Example 4.7 (Maximum Range of a Projectile with animations) Galileo, in his book Two new sciences, stated that “for elevations which exceed or fall short of 45° by equal amounts, the ranges are equal”. Prove this statement.
