A body is thrown vertically upward with velocity 20m/s .How long time it remains in air? (g=10m/s2)

Given:

Velocity (u) = 20 m/s

Acceleration due to gravity (g) = 10

To Find:

Time (t) being in which body remains in air.

Explanation:

Formula:

Substituting values of u & g in the equation:

Time (t) being in which body remains in air = 4 seconds

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
