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?

Explanation:

Given that,

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

Acceleration of the object,

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

t = 1 second

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

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
