| im stuck trying to figure out how to solve this physics problem |

--- 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? --- End quote --- 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 |
