A 0.4 kg ball is thrown straight up into the air with a velocity of 12.2 m/s. What maximum height will it reach?

Maximum height is 7.59 m.

Explanation:

We have,

Mass of a ball is 0.4 kg

It is thrown straight up into the air with a velocity of 12.2 m/s.

It is required to find the maximum height reached by the ball.

Concept used : Law of conservation of energy.

Solution,

Here, the energy of the ball remains conserved. Let h is the maximum height reached by the ball such that,

So, the maximum height reached by the ball is 7.59 m.

the higher the current the higher the mag field around it the higher the influence on the compass
