A 2kg box is being pulled up a ramp by a force of 24N. The ramp is at an angle of 35 degrees from the ground. The force of friction on the box is 1.5N. What is the magnitude and direction of the component of gravity in the x-direction?

Need in all of themmm only answer if you know plsssss

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
