An ice skater starts with a velocity 2.25 m/s in a 50.0 degree direction after 8.33s she is moving 4.65 m/s in a 120 degree direction what is the x-component of her acceleration

Explanation:

To answer the question, we just need to consider the motion along the horizontal direction.

The component of the initial velocity of the ice skater along the x-direction is:

where u = 2.25 m/s is the initial velocity and is the angle.

The component of the final velocity of the ice skater along the x-direction is

where u = 4.65 m/s is the final velocity and is the angle.

The acceleration along the x-direction is given by

where

t = 120 s is the time

Substituting,
