Question

At t =0s, an object is moving to the right with a velocity v that can be modeled by the equation v =(4.2 m/s) - (1.4 m/s²). What is the initial velocity of the object?

Answer 1

At t = 0s, the initial velocity of the object from the provided equation is 4.2 m/s.

Step-by-step explanation:

The initial velocity of the object when t = 0s is provided by the velocity equation v(t) = v0 + at, where v0 is the initial velocity, a is the acceleration, and t is the time. In your given equation, v = (4.2 m/s) - (1.4 m/s²), the initial velocity is represented by the first term 4.2 m/s and is constant since acceleration term has t² and initial time is 0. Thus, the initial velocity of the object is 4.2 m/s.
