Block pushed up 35degree incline (frictionless)

[bustin]

1. a block is pushed up a 35 degree incline (no friction) by an applied force. If F= 20N and m= 2.0kg, what is the magnitude of the resulting acceleration of the block?



2. not sure?
f=ma



3. don't know where to start. It has been a long time since physics

Remember SOH, COH, TOA

Welcome to PF.

Start by drawing a free body diagram.

You have gravity of g acting straight down. What component of gravity then is acting down the incline?

And how might this weight component act with respect to the force pushing up the incline?
