Calculate the acceleration of the object during the first two seconds

The acceleration of the object during the first two seconds  is 1.5 .

Explanation:

At t = 2 s, velocity of the object is 3 m/s

At t = 0 s, velocity of the object is 0 m/s

Acceleration is define as rate of change of velocity with time.

∴Acceleration =

Acceleration =

Acceleration =

Acceleration = 1.5

The acceleration of the object during the first two seconds  is 1.5 .

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
