Calculating Horizontal Distance of a Stunt Rider

Explanation:

To calculate the horizontal distance that the stunt rider will land from the base of the cliff, we can use the formula for horizontal motion, which is distance = speed × time. Since there is no horizontal acceleration in this problem (we're ignoring air resistance), the horizontal speed remains constant at 15 meters/second throughout the motion.

Given that the horizontal speed (v) is 15 meters/second and the time (t) is 0.8 seconds, we can calculate the horizontal distance (d) the stunt rider will cover before landing.

Horizontal Distance Calculation:

Distance (d) = Speed (v) × Time (t)

d = 15 m/s × 0.8 s

d = 12 meters

The stunt rider will land 12 meters away from the base of the cliff.
