Ahiker hikes in a straight line and maintains a constant velocity of +0.5 m/s. at time t=0.0 s, the hiker is 30 m from point a. what is the displacement from point a at 120 s?

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

d

explanation:

v=uf/(u-f)
