--- Quote ---Suppose that you are standing on a skateboard near a wall and that you push in the wall with a force of 30 N if your mass is 60kg what is your acceleration?

like how do you solve this? what formula do you use?

Gytyyhgfffff:

this is the equation we're going to use
f = ma

we know the force is 30 N and the mass is 60 kg so we can substitute those in directly

30 = 60a

now we solve for a which is acceleration

30 / 60 = a
0.5 = a
since acceleration is measured in m/s² the real answer is 0.5 m/s²

i don't know if that's right i only got a 3 on the ap physics exam but i'm pretty sure that's how you do it

Tactical Nuke:

if it's talking about instantaneous acceleration then that's correct

yeah .5 is the answer but thanks for showing how to solve it
