Hello!
Begin by finding the acceleration of the puck. Use the kinematic equation:
The initial velocity is 0 m/s since the object was at rest, so we can rewrite the equation as:
Plug in the given distance and time:
Find the net force using the formula F = m · a (Newton's Second Law)
F = 0.18 · 0.1
F = 0.018 N
