Many birds can attain very high speeds when diving. Using radar, scientists measured the altitude of a barn swallow in a vertical dive; it dropped 208 m in 3.0 s. The mass of the swallow was estimated to be 0.018 kg, and its cross-section area as 5.6 x 10-4 m2. What was the drag coefficient for this swallow as it dove?

At an accident scene on a level road, investigators measure a car's skid mark to be 88 m long. It was a rainy day and the coefficient of friction was estimated to be 0.35. a.)Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes. Express your answer to two significant figures and include the appropriate units.
Physics The lock down has made mellisa soft. She gets caught the last time she tries to steal a box of red vines, so mallisa decides she needs to start working out. Since gyms are so expensive, mallisa decides to practice pushing a 100 kg box filled with chemistry textbooks place of red vines) across her living room and back, a distance of 30 m. If mellisa pushes with a force of 875 N at an angle 25 degrees below the horizontal, what was the amount of work that mellisa performed on the box? a)-23.800J b) -13,600J c)31,200J d) 23,800J
6. Son Ye Jin (SYJ), 45 kg, drops from a helicopter 4 km above the ground. Assume the air resistance is proportional to the velocity of the SYJ, with k 15 N-sec/m when the chute is closed and with constant k₂ = 105 N-sec/m when the chute is open. If the chute does not open until 1 min after SYJ paraglides, when will she hit the ground?
The conveyor belt is designed to transport packages of various weights. Each 10-kg package has a coefficient of kinetic friction u. = 0.31.

A frictionless plane is 10.0 m long and inclined at 30.0°. A sled starts at the bottom with an initial speed of 5.30 m/s up the incline. When the sled reaches the point at which it momentarily stops, a second sled is released from the top of the incline with an initial speed v₁. Both sleds reach the bottom of the incline at the same moment. (a) Determine the distance that the first sled traveled up the incline. m (b) Determine the initial speed of the second sled. m/s
Just like Louis, Maria left a book on the roof of her car before driving away. The mass of the book was 725 grams. The coefficient of static friction between the book and the roof was 0.28. The coefficient of kinetic friction between the book and the roof was 0.23. Maria started her car and drove forward on level ground with an acceleration of 3.6 m/s?. As Maria was driving away with that acceleration, what was the magnitude of the force of friction (in newtons) between the book and the roof of the car?
ents Once I went skiing. I was at the bottom of a snow ramp with a speed of 14.0 m/s. Assuming that the coefficient of friction between the snow and the skis was 0.2 determine my speed at the top of the ramp. The angle theta with the horizontal was 25°. The rise of the snow ramp was h=3.5 meters high. h Skier Met < Previous OL 1
