D.
A driver forgets to engage the parking brake and his car rolls downhill after he parks.
The peregrine falcon is known to be the fastest animal on earth, reaching a top speed of 240 mph when hunting. When doing so, it does not flap its wings. Rather, it relies upon the gravitational force to accelerate it downwards.
Assuming that it starts from rest, and assuming that drag forces are minimal, how long does it take for the hawk to reach its top speed? b. How far does it travel during this time? c. Near the top speed, drag forces become important, and in fact the terminal velocity is determined by the drag force. Assuming that the hawk’s body can be modeled as a cylinder, with its cross-sectional area equal to that of a circle with radius of 10 cm, what is the coefficient of drag ? for a hawk?

It would actually be safest to drive at the design speed, but you have to drive more slowly, because there are slow-moving cars in front of you. In this case, you need help from friction to successfully get around the curve. 1) Draw Free Body Diagram for this scenario 2) Calculate Maximum Speed ( g = 10 m/s2; r = 160 m; tangent of the angle = 1/4 (this corresponds to an angle of 14 degrees); coefficient of static friction = 0.20. If the tangent of the angle is 1/4, then the sine of the angle divided by the cosine of the angle is 1/4, which means that the cosine of the angle is 4 times the sine of the angle). Maximum Speed = 27.5 m/s, calculate how you get this.arrow_forward
