Question

What is the speed of an apple dropped from a tree after 1.5 second? What distance will it cover during this time?Take g=10m/s² (Ans:15m/s; 11.25m)

Answer 1

Let the velocity by which the Apple is moving me v ms.

Initial Velocity of the speed(u) = 0

Time taken by the Apple to fall = 1.5 s.

Using the Galileo's First Equation of the motion,

v - u = at

∴ v - 0 = 10 × 1.5

⇒ v = 15 m/s.

Hence, the velocity of the Apple is 15 m/s.

Hope it helps.

Answer 2

Thanks for the question!

It is definitely a very interesting question to solve and do some brainstorming.

**************************************************

Let the velocity of Apple be "v" m/s

Let the Initial Velocity of the speed be "u" m/s

Time taken by the Apple to be dropped from tree = 1.5 s

Accelaration is "a" measured in metres per second

We know, Galileo's First Equation of the motion,

v - u = at

v - 0 = 10 × 1.5

v = 15 m/s.

So, Velocity of the Apple is 15 m/s.
