Question

REALLT NEED HELP PUT MOST POINTS IN!

the following formula relates tree quantities: Force (F), mass (M) and acceleration (A)
F=ma
steps i need help with
1. solve this equation for A
2. let the force be F= -25 unites and the mass be M =10 units. what is the acceleration?
3. let the force be F =25 units and acceleration be a = 5 untitled. what is the mass?

Answer 1

1. To solve for a you need to take out any variable that is with it. F=ma, so divide by m on both sides to get F/m=a.

2. Use the previous formula/equation for this. Plug in the numbers, so -25/10=-2.5 units.

3. You're looking for the mass, so you do the same thing to the previous formula. F=ma, so divide F by a to bring it to one side, isolating m. F/a=m, plug in numbers, 25/5=5 units.
