Question

According to legend, Galileo dropped two balls from the Tower of Pisa to see which would fall

faster. Suppose one of the balls had a mass of 5.0 kilograms. Given the acceleration of gravity is 9.8m/sec?, what was the weight of the ball in newtons?

Answer 1

Answer: 4.9 N

Step-by-step explanation:

Weight
`W` is the force that gravity exerts on matter and changes depending on where the body is located. This means, the weight of an object on Earth will not be the same as the weight of the same object on the Moon or on Mars.

Well, in the case of Galileo, he performed his experiment on Earth. Hence, the acceleration due gravity is
`g=9.8 m/s^(2)`.

In addition, weight is mathematically expressed as:

`W=m.g`

Where
`m=5 kg` is the mass of the ball

Solving the equation:

`W=(5 kg)(9.8 m/s^(2))`

`W=4.9 N` This is the weight of the ball
