A horse was pulling a wooden block along a section of horizontal ground. The pulling force of the horse was 22 kg-wt which was acting on the block at an angle of to the vertical. Given that the block was moving uniformly, determine the magnitude of the friction acting on the block.
A body weighing is moving at a constant speed on a horizontal plane under the action of a force 145 N whose line of action is inclined at an angle to the horizontal, where . If the resistance of the plane to the body’s motion is , find and the normal reaction of the plane .
