Determining Olympic Skier Tina Maze's Speed After 4.0 Seconds

How do you determine Tina Maze's speed 4.0 seconds after starting?

Given the acceleration of 4.1 m/s², how can we calculate Tina Maze's speed after 4 seconds?

Answer:

To determine Tina Maze's speed after 4.0 seconds with a constant acceleration of 4.1 m/s², use the equation v = at, which yields a speed of 16.4 m/s.

Explanation: The student is asking how to determine the speed of Olympic skier Tina Maze 4.0 seconds after starting from rest, given a constant acceleration of 4.1 m/s². To find the speed after a certain time with constant acceleration, we use the kinematic equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time. Assuming Tina Maze starts from rest (u = 0), the equation simplifies to v = at.

Using the given values, the calculation becomes:

v = 4.1 m/s² × 4.0 s = 16.4 m/s.

Tina Maze's speed after 4.0 seconds would therefore be 16.4 m/s.
