There must be a force applied, and there must be motion in the direction the force acts. You have to specify the direction because, for example, consider a satellite in a circular orbit. There's always a gravitational force on it, toward the center of the Earth, but the satellite never moves in that direction, so gravity does NO WORK on the satellite.

The position of a ball as a function of time is given by
Andre45 [30]

Answer:

x = -6.5 meters

Explanation:

The position of a ball as a function of time t is given by :

x=3\ m+(-5\ m/s)t..................(1)

Where t is time in seconds

We need to find the position of the ball at 1.9 s. It can be simply calculated putting t = 1.9 s in equation (1) as :

x=3+(-5)(1.9)

x = -6.5 meters

So, the position of the ball at 1.9 seconds is -6.5 meters. Hence, this is the required solution.
