Final answer:

The magnitude of the acceleration of the skier is 2 m/s².

Step-by-step explanation:

The magnitude of the acceleration of the skier can be found using the formula:

acceleration = (final velocity - initial velocity) / time

In this case, since the skier starts from rest, the initial velocity is 0 m/s. The final velocity can be found using the equation:

final velocity = (displacement) / time

Plugging in the values given, the final velocity is (50 m) / (5 s) = 10 m/s. Substituting the values into the acceleration formula, we get:

acceleration = (10 m/s - 0 m/s) / (5 s) = 2 m/s²

Answer:

See below

Step-by-step explanation:

d = 1/2 at^2

50 = 1/2 ( a) 5^2

4 m/s^2 = a
