An object dropped from a leaf false with a constant acceleration of 10 m/s2. Find its Speed 2 second after it was dropped.

 An object dropped from a leaf false with a constant acceleration of 10 m/s². Find its Speed 2 second after it was dropped.

                          

Solution:

Given:

• Initial speed, $u = 0$ (object is dropped)

• Acceleration due to gravity, $a = 10 \, \text{m/s}^2$
  

• Time, $t = 2 \, \text{s}$

Formula used:

$$v=u+at$$

Calculation:

$$v=0+(10\times 2)=20\text{m/s}$$

Answer:

• The speed of the object after 2 seconds is 20 m/s (downwards).
