Question

A stone is thrown in a vertically
upward direction with a velocity
of 5 ms. If the acceleration of the
stone during its motion is 10m s-2
in the downward direction, what
will be the height attained by the
stone and how much time will it
take to reach there?​

Answer 1

Answer:

1.25 metres

Explanation:

Given :

• Initial velocity = u = 5 m/s

• Acceleration during upward motion = a = -10 m/s²

To find:

• Maximum height attained by the stone

We know that formula for maximum height attained by an object = u²/2g

Here, u = 5 m/s

g = 10 m/s²

Maximum height = 5²/2×10

Maximum height = 25/20

Maximum height = 1.25 metres

The maximum height attained by the object is equal to 1.25 metres
