Question

If a body of mass 2 kg play they had a height of 3 metre is dropped what will be the velocity when it hit the ground​

Answer 1

Answer:

Given:

Initial velocity, u = 0m/s

Mass, m = 2kg

Height, s = 3m

Acceleration, a= 9.8m/s²

To Find:

Final velocity, v = ?

Solution:

v² = u²+ 2as

➡ v² = 0 + 2×9.8×3

➡ v² = 58.8

➡ v = √58.0

➡ v = 7.668~

So, final velocity when it touches the ground will be 7.668m/s.
