Question

A hockey puck with a mass of 0.16 kg is sitting at rest on a frozen pond. Suddenly, the wind begins to blow, accelerating the puck across the ice at 625 m/s2. If friction is ignored, the force of the wind can be calculated to be _______.
A. 625.16 N
B. 3,906 N
C. 0.000256 N
D. 100 N

Answer 1

Answer:

Given that : m=. 16kg

a=625m/s^2

$force = mass \times acceleration \\ \: \: \: \: \: \: \: \: \: \: \: \: \: f = m \times a$

Putting the values of a&m

We get, f=. 16×625

=100N ans.
