Document Summary

Consider a pilot ying at 2200 km/h (2. 2 103 km/h) steering into such a turn. What is the minimum radius he needs to follow to avoid a black-out: [5] a roller coaster track as shown in the gure is designed such that a car travels upside down when at the top. Start with a free-body diagram and explain your steps. Calculate the gravitational attraction that m2 and m3 exert on m1. Start with a drawing indicating the positions of the masses and the force vectors acting on m1. 2: a car is pushed along a long road that is straight, at, and parallel to the x direction. 2 a t2 f (t) dt = t2 f (t) dt = at + c f (t) = anti-derivative = inde nite integral g = 9. 8 m/s2. E (cid:126)fd (cid:126)v; linear: fd = dv; quadr. : fd = 0. 5 av2; a = cross s"n area; = density of medium.

1. An object of mass 19 kg is placed on incline with friction.The incline is originally horizontal and then raised slowly and at21 degrees, the mass begins to slide down the incline. It is foundthat the coefficient of kinetic friction is 0.79 times thecoefficient of static friction. If the same object (same mass) isplaced on the same incline with an inclination angle of 42.2degrees (the mass will slide down the incline at this angle), whatis the magnitude of the acceleration on the mass in m/s2?
2. A mass enters the bottom of a 50 degree incline with acoefficient of kinetic friction of 0.6. At the bottom of theincline the mass is moving at 33 m/s and is moving up the incline.After the mass has traveled, 25 meters up the incline, what is themagnitude of its velocity in m/s?
3. A car is traveling around a circular, banked track withoutfriction. It is initially traveling around the bottom of the ramp(on the ground) where the inner radius of track is 351 meters. Thecar then increases its velocity by a factor of 1.7. If theinclination angle is 10 degrees, what is the height (verticaldistance above the ground) the car is traveling at this newvelocity. Answer in meters.
4. An yo-yo with a mass of 2.4 kg is swung in a vertical circle. Itis found that the string breaks at 228 Newtons. If its the yo-yo'sspeed is a constant and is the maximum speed the yo-yo can movebefore the string breaks, what is the the tension in the string atthe top of the circle in Newtons?
5. A roller coaster cart of mass 15.8 kg travels on the inside of aroller coaster track in a loop of radius 23.1 meters. The circle isa vertical circle similar to the yo-yo example done in class. Ifthe cart travels at a constant speed around the track and the valueof this speed is the minimum speed such that cart does not fall offthe track at the top of the track, was is the magnitude of thenormal force on the cart at the bottom of the track in Newtons?
