(25%) Problem 2: Suppose the ski patrol lowers a resese sled carrying an injured skier with...
Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 95.0 kg, down a θ = 68.0° slope at constant speed, as shown in Figure 6.22. The coefficient of friction between the sled and the snow is 0.100.(a) How much work is done by friction as the sled moves 30.0 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 gravity...
Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 80.0 kg, down a θ = 70.0° slope at constant speed, as shown in the figure. coefficient of friction between the sled and the snow is 0.100. (a) How much work is done (in J) by friction as the sled moves 30.0 m along the hill? -805.25 J (b) How much work is done (in J) by the rope on the sled in this distance?...
Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 55.05 kg, down a theta= 64.84º slope at constant acceleration a=-2.00 m/s2, as shown in Figure. The positive direction is downward along the slope. Hence, the negative sign in acceleration, if present, means the direction of the acceleration is pointing along the slope upwards. The coefficient of friction between the sled and the snow is 0.100. How many Joules of work is done by the...
