An object of mass 5 kg is acted upon by exactly four forces,, each of magnitude 10 N. which of the following could NOT be the resulting acceleration of the object?

Options

A. `0m//s^(2)`
B. `2m//s^(2)`
C. `4m//s^(2)`
D. `10m//s^(2)`

Answer

D

Explanation

The maximum net force on the object ocurs when all four forces act in the same direction, given `F_("net")=4F=4(10N)=40N`, and a resulting acceleration of `a=F_("net")//m=(40N)//(5kg)=8m//s^2`. These four forces could not give the object an acceleration greater than this.
