In a game, a character jumps from a height of 10 meters. Assuming no air resistance, what is the character's velocity when it hits the ground?

A
28 m/s
💡 Explanation:
The character's velocity when it hits the ground can be calculated using the equation: v^2 = u^2 + 2as, where v is the final velocity, u is the initial velocity (0 m/s), a is the acceleration due to gravity (9.8 m/s^2), and s is the distance fallen (10 m). Plugging in these values, we get: v^2 = 0^2 + 2 * 9.8 * 10, which simplifies to v^2 = 196. Taking the square root of both sides, we get v = 14 m/s.
