**Problem Statement:**A horse pulls a 300 kg sled for 50 m over level ground at constant speed, exerting a force of 3000 N at 30° above the horizontal. How much work is done by the horse on the sled?**Options:**- 150 kJ- 2940 J- 130 kJ- 0 J**Explanation:**To find the work done by the horse, we can use the formula:\[ \text{Work} = F \cdot d \cdot \cos(\theta) \]Where:- \( F = 3000 \, \text{N} \) (the force exerted by the horse)- \( d = 50 \, \text{m} \) (the distance over which the force is applied)- \( \theta = 30^\circ \) (the angle above the horizontal)Calculating the component of the force in the direction of the movement:\[ \text{Work} = 3000 \, \text{N} \times 50 \, \text{m} \times \cos(30^\circ) \]\[ \text{Work} = 3000 \, \text{N} \times 50 \, \text{m} \times \frac{\sqrt{3}}{2} \]\[ \text{Work} = 3000 \times 50 \times 0.866 \] \[ \text{Work} = 129900 \, \text{J} \]Since 1 kJ = 1000 J:\[ \text{Work} = 129.9 \, \text{kJ} \]Therefore, the closest option is 130 kJ.

The (non-conservative) force propelling a 1.40 x 103-kg car up a mountain road does 6.90 x 106 J of work on the car. The car starts from rest at sea level and has a speed of 28.0 m/s at an altitude of 2.40 x 102 m above sea level. Obtain the work done on the car by the combined forces of friction and air resistance, both of which are non-conservative forces. Number Units
