Question

A Skier descended down a mountain at a rate of 14 feet per second.what was his total change in elevation after 8 seconds?

Answer 1

1.75ft/s²

Explanation:

The total change in elevation of the skier is its acceleration. Acceleration is the change in velocity of a body with respect to time.

Acceleration = Velocity/Time

Given velocity of the skier = 14feet/sec

Time taken = 8secs

Acceleration of the skier = 14/8

Acceleration of the skier = 1.75ft/s²

Hence the total change in elevation after 8 seconds is 1.75ft/s²
