Homework Statement
Block A is traveling down an incline plane of 35 degrees at 2m/s. It's pulling a 4kg block with a pulley and rope. Coefficient of friction is.12. How heavy must block A be ?
Homework Equations
F=MA
F = WsinΦ + μWcosΦ
mgh = 1/2 mv^2 + WD to overcome friction
Vf^2 = u^2 + 2as
The Attempt at a Solution
I'm having a hard time thinking through this question. I know how to find the forces on an inclined plane and I understand that it needs to overcome the force of the 4kg block and accelerate it to 2m/s. Whenever I see velocity I automatically think of the linear velocity and acceleration equations. I'm not even sure where to begin. I've tried the above equations but it seems like I'm always missing a value. If someone could point me in the right direction I will try and post on here.
thanks
