A 53 kg woman athlete can generate a sustained specific power output of 5.0 W/kg. One training exercise is to push a heavy sled across the grass at a steady speed, which takes a horizontal pushing force of 147 N.

Based on the given information, we can calculate the power output of the woman athlete while pushing the sled.
First, we need to calculate the total force applied by the athlete, which is the pushing force required to move the sled. The pushing force is given as 147 N.

Next, we need to calculate the work done by the athlete, which is the product of force and distance. Since the speed is steady, we assume there is no acceleration, and thus no change in kinetic energy. Therefore, the work done is equal to the force applied multiplied by the distance covered.
Since the speed is constant, we can assume that the force applied is equal to the frictional force opposing the motion of the sled. This force is equal to the weight of the sled, which can be calculated as the mass of the sled multiplied by the acceleration due to gravity.
Now, we can calculate the distance covered by the athlete. Since the speed is steady, the distance covered is the product of the speed and time.Based on the given information, we can calculate the power output of the woman athlete while pushing the sled.
First, we need to calculate the total force applied by the athlete, which is the pushing force required to move the sled. The pushing force is given as 147 N.
Given that the woman athlete has a sustained specific power output of 5.0 W/kg, we can calculate her power output by multiplying her body weight by the specific power output.
In conclusion, to calculate the power output of the woman athlete while pushing the sled, we need to calculate the total force applied, the distance covered, and multiply her body weight by the specific power output.
