The diagram shows an inclined slope, at an angle of 25 degrees, the mass of the object is 3kg, and the force acting up the slope is 24N
a) Calculate the acceleration of the block up the the slope, assuming no friction forces act on the slope
b) If the 24N force is removed, what would be the deceleration of the block?
c)As the block accelerates down the slope, the surface changes and a large force is eencountered so that the block moves with constant velocity. What is the magnitude of the fricton force that causes this motion?
For a) I got 3.85ms-2
b) I got 4.15ms-2
c) i got 1N
However i do not know if these answers are correct, thank you for your help, it would be a pleasure if you would work these out, with the correct values..
