Q6). Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 95.0 kg, down a 60° slope at constant speed, as shown in Figure 1 below. The coefficient of friction u between the sled and the snow is 0.150 b a). How much work is done by friction as the sled moves 50.0 m along the hill? b). How much work is done by the rope on the sled in this distance ? c). What is the work done by the gravitational force on the sled ? d). What is the total work done? The acceleration due to gravity is 10 m/s2 60

Answer rating: 100% (QA)

The rope is doing work against the gravity The friction always acts against the direction of motion View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
