° to the horizontal. Find the acceleration of the block and the force of friction acting on it.

First, we need to resolve the pulling force into its components:

F_parallel = 1000 cos(30°) = 866 N (parallel to the plane)
F_perpendicular = 1000 sin(30°) = 500 N (perpendicular to the plane)

The weight of the block is 2500 N, so the net force acting on the block in the direction of the pulling force is:

F_net = F_parallel - friction = 866 - (0.2)(2500) = 366 N

Using Newton's second law (F = ma), we can find the acceleration of the block:

a = F_net/m = 366/2500 = 0.1464 m/s^2

The force of friction acting on the block is:

friction = coefficient of friction x normal force
= 0.2 x weight of block
= 0.2 x 2500 = 500 N

Therefore, the force of friction acting on the block is 500 N.
