Question

A truck has a force of 2000 newtons and is moving 10 miles per hour. How much mass does the truck have?

Answer 1

Force= Mass×Accelaraion

F=m×a

The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²

we have 10mph = 4.47 meters per second square

2000N= m×4.47m/s²

= 2000/4.47m/s²=m

= 447.42

Answer 2

Force= Mass×Accelaraion

F=m×a

But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²

Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)

So now we have,

2000N= m×4.47m/s²

= 2000/4.47m/s²=m

= 447.42

Thus the mass of the object is 447.42 (i am not sure of units)
