A jogger exerting a force of 29N against air resistance while maintaining a velocity of 4.0m/s expends energy at a rate calculated using the formula P = F * v. The correct calculation yields P = 29N * 4.0m/s, resulting in a power output of 116 Watts. The initial attempt incorrectly referenced units, as power is measured in Watts, not kgm/s.
PREREQUISITESPhysicists, sports scientists, fitness enthusiasts, and anyone interested in understanding the mechanics of running and energy expenditure against air resistance.
The units are wrong for power. What do you get if you multiply Newtons by m/s?Nick1234284 said:1. Suppose a Jogger has to exert a force of 29N against air resistance to maintain a velocity of +4.0m/s. At what rate is the jogger expending energy?2. P= F*(tf-ti)3. Attempt solution was
P= 116kgm/s
