Question

u dropped a pen from the table,of height 1 meters such that it accelerates at 10m/s².using the equations of motion,find the velocity with which it will hit the floor​

Answer 1

Answer:

Provided that:

• Distance = 1 metre
• Initial velocity = 0 mps
• Acceleration = 10 m/s sq.

To calculate:

• Final velocity

Solution:

• Final velocity = 4.47 m/s

Using concept:

• Third equation of motion

Using formula:

• v² - u² = 2as

Where, v denotes final velocity, s denotes displacement or distance or height, a denotes acceleration and u denotes initial velocity.

Required solution:

→ v² - u² = 2as

→ v² - (0)² = 2(10)(1)

→ v² - 0 = 2 · 10 · 1

→ v² = 20

→ v = √20

→ v = 4.47 m/s

→ Final velocity = 4.47 m/s $\:$
