Question

Shania went to an orange farm during her visit to Orlando. An orange with a mass of x kilograms dropped from a tree and landed on her foot. Which expression represents the orange's force if the acceleration is 9.8ms2?

select the answer

- x/9.8 N
-9.8/x N
-9.8x N
- 9.8x^2 N

Answer 1

The expression represents the orange's force is
`9.8x\ N`

Solution:

Given that, Shania went to an orange farm during her visit to Orlando

An orange with a mass of x kilograms dropped from a tree and landed on her foot

Given that, acceleration is
`9.8\ m/s^2`

To find: Expression that represents force

By newton second law of motion,

`Force = mass * acceleration`

From given,

`mass = x\ kilograms\\\\acceleration = 9.8\ m/s^2`

Therefore,

`Force = x * 9.8\\\\Force = 9.8x`

The the unit of force is newton

Therefore, the expression represents the orange's force is
`9.8x\ N`
