Writing the sum of the forces down the slope....

Weight*sinTheta-Windfriction=mass*acceleration.

In the first part, a=0

so..

35*sin(11)-Fx=0

and solvee for Fx?

.. as for the increasing rate.. is it telling me that the 1.0m/s2 is added to the gravity of 9.8m/s2?

**JT**, Wednesday, February 9, 2011 at 2:20pmthis is kinda late answer, but still...

35*sin(11)-Fx=0

This works for a = 0

35*sin(11)+ma-Fx=0

More complete answer... (a!=0)

So, for increasing rate of a = 1m/s^2

This is going in negative direction, so

35*sin(11)+(35)(1)=Fx

And for a = 22/s^2

35*sin(11)+(35)(2)=Fx

Crunch in calculator for Fx in Newtons

**JT**, Wednesday, February 9, 2011 at 2:22pmActually, just noticed that was for in -x direction, so change sign on acceleration

35*sin(11)+(35)(-1)=Fx

35*sin(11)+(35)(-2)=Fx

**stuff**, Thursday, September 12, 2013 at 9:23pmur supposed to multiply the 35sintheta with the acceleration due to gravity (9.8)
