At a certain instant an object is moving to the right with speed 1.0 m/s and has a constant acceleration to the left of 1.0 m/s2. At what later time will the object momen- tarily be at rest?

Respuesta :

Explanation:

Given that,

Initial speed of the object, u = 1 m/s

Acceleration of the object, [tex]a=-1\ m/s^2[/tex]

We need to find the time when the object comes at rest (v=0). Let it is given by :

[tex]t=\dfrac{v-u}{a}[/tex]

[tex]t=\dfrac{0-1\ m/s}{-1\ m/s^2}[/tex]

t = 1 second

So, the object will comes to rest at 1 second. Hence, this is the required solution.
