Urgent! Acceleration of an ice block given mass
A 42 kg block of ice slides down a slope of 30 degrees. Assuming friction is negligible, what is the acceleration of the block down the incline?
Fnet=max
W=mg
I have drawn a free body diagram correctly. I have the block on a slope of 30 degrees. I have weight acting downward and Normal Force acting perpendicular to the slope. I just want to make sure that I am doing this right.
Fnet=max
I know I have mass already and I can get weight by multiplying 42 by 9.8 m/s2
My problem is what numbers would I use for Fnet? Just the X component for weight or also the Y component?
