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

The expression represents the orange's force is

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

To find: Expression that represents force

By newton second law of motion,

From given,

Therefore,

The the unit of force is newton

Therefore, the expression represents the orange's force is

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
