Question

If you drop a ball off a cliff, it starts out at 0 m/s. after 1 s, it will be traveling at about 10 m/s. if air resistance is removed, what will happen in 2 s?

Answer 1

The ball dropped of a cliff will have a final velocity of 19.6 m/s at 2s

The free fall formula and the procedure we will use is:

fv = g* t

Where:

• fv = final velocity
• g = acceleration due to gravity
• t = time taken
• h = height traveled

Information of the problem:

• g = 9.8 m/s².
• t = 2 s
• vf = ?

Applying final velocity formula we get:

fv = g* t

fv = 9.8 m/s² * 2 s

fv = 19.6 m/s

What is free fall?

It is when the object or mobile falls from a height (h) with a positive acceleration equal to the gravity, describing a vertical rectilinear travel.
