No friction present means: Ek = Ep
So Ek = mgh = 10 * 9.8 * 2 = 196 J
If its accelerating it will increase velocity in the direction of the acceleration which is perpendicular to the velocity.
Answer: Productivity increases when inputs and outputs increase proportionately.
Explanation:
Productivity increases when inputs and outputs increase proportionately. Input has to be directly proportional to output to be productive. This means increase in input to a system must leads to drastic increase in the output. When the output is not balanced with the amount of input, it leads to unproductivity.
Being productive can be business wise or in terms if personal growth and development.

Explanation:
A student practicing for a track meet, ran 250 m in 30 sec. a. What was her average speed? 250 m = 8.3 m/sec 30 sec.
Gravitational force between two masses is given by formula

here we know that




now from the above equation we will have


so above is the gravitational force between car and the person
