The Answer is B. 25 Newtons. 10 x 2.5 = 25.  M/s x Kg = N

2. idontknow1993 says:

The correct answer is 1242 N

I cannot eliminate B by any method but to say that you cannot manufacture an extra m in an equation. So B is wrong.

The original equation is F = m * aif you want m by itself, you must divide both sides of the equation by aF/a = m*a/a        Do the divisionF/a = m               the "a"s cancel.So D turns out to be the answer.

C divides only once side by F. It is an unbalanced operation

A does some sort of mathematical slight of hand. Good for magicians, bad for physics students. I don't know how A is justified. It's just wrong.

Formula

F= ma

Givens

m = 10 kga= 2.5 m/s^2

Solution

F = 10 * 2.5F = 25  Newtons

C

In order to determine mass, you would need to isolate m, in other words keep it alone (m =). However, it can be quite tricky at first glance to do this. Simply divide A by both sides to isolate the m.

F = Ma

M needs to be isolated.

Divide A by both sides to isolate M.

F/a = m

M = F/a

D. m= F/a

B

Explanation:

JUST MULTIPLY THE MASS(3.4)×ACCELERATION(8.1)

AND YOU GET THE ANSWER IN NEWTONS
