Compute all parts of given question:
Question: Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60 kg runner completes a 5.0 km race in 19minutes.
Part I: Determine the drag force on the runner during the race. Suppose that the cross section area of the runner is 0.72 m2 and the density of air is 1.2 kg/m3.
Part II: What is this force as a fraction of the runner's weight?
I need help to find the drag force on the runner during the race.
The tortoise can run with a speed of 0.1 m/s and the hare can run with a speed of 2 m/s. They start their race at the same time, but the hare, feeling confident, stops along the way for a two minute nap, and the tortoise wins by the length of his ..
A uniform magnetic field is perpendicular to the plane of acircular loop of diameter 12 cm formed from wire of diameter 3.5 mmand resistivity of 2.11 x 10-8Ω·m. At what rate must the magnitude of the magnetic field change to induce a9.5 A current..

Suppose he enters the water at a speed of 16.0 m/s via path 1. Explain how fast is he moving on path 2 when he releases the rope at a height of 4.00 m above the water? Ignore the effects of air resistance.
A pipe is opened at both ends. Its length is 22.81cm. If i excite standing waves in the pipe by blowing air over one of its ends, I hear a pitch of 712.5 Hz. a) find the distance between the antinodes at the two ends of the pipe.
A car weighing 1.1×104 N and traveling at 12.90 m/s attempts to round an unbanked curve with a radius of 54 m. What force of friction is required to keep the car
Two forces, 375 N at 11deg and 323 N at 25deg are applied to a car in an effort to accelerate it. If the car has a mass of 3730kg, what magnitiude of acceleration does it have
