Question

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

x=3.0m+(−5.0m/s)t
What is the position of the ball at 1.9 s ?

Answer 1

x = -6.5 meters

Step-by-step 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.
