Question

A steel ball of mass 100 g is thrown horizontally with a velocity of 100 km/h from the top of a 75 m high tower. Draw a diagram to show its path of entire journey

Answer 1

Answer 2

Explanation:

Given that,

The mass m = 100 g

Velocity v = 100 km/h

Height h = 75 m

A steel ball is thrown in horizontally.

So, The horizontal component of the velocity will be same as initial velocity.

The ball will fall on the ground at a distance equal to range.

The range given by

$R = u\times(\dfrac{2h}{g})^{\dfrac{1}{2}}$

$R= 100\times\dfrac{5}{100}\times(\dfrac{2\times75}{9.8})^{\dfrac{1}{2}}$

$R = 19.56\ m$

The range is 19.56 m.

Therefore,

The diagram to show its path is parabola.
