Question

A meter stick whose mass is 260 grams lies on ice. You pull at one end of the meter stick, at right angles to the stick, with a force 6 newtons. The ensuing motion of the meter stick is quite complicated, but what are the initial magnitude and direction of the rate of change of the momentum of the stick, , when you first apply the force?

Answer 1

a = d p / dt = 23 m / s², The direction is the direction of the force

Step-by-step explanation:

Newton's second law can be written in the form

F = dp / dt

How the body is initially at rest

F = m a

a = F /m

a = 6 /0.260

a = 23 m / s²

a = d p / dt = 23 m / s²

The direction is the direction of the force
