- A car of massm travels around a flat, circular curve of radius r at the fastest possible speed, v = 13.5 m/s without sliding off. The car and road have a coefficient of friction, between them. If the car wishes to take the turn at 2.4x the velocity, by what factor would the radius need to increase (so the car doesn't slide off) ? Give your answer to 1 decimal place.A 1,669 kg automobile is moving at a maximum speed of 27 m/s on a level circular track of radius 88 m. What is the coefficient of friction?In an amusement park ride, riders stand against the wall of a spinning cylinder. The floor falls away and the riders are held up by friction. If the radius of the cylinder is 4 m, find the minimum number of revolutions per minute necessary when the coefficient of friction between a rider and the wall is 0.4.
- Redo Example 5, assuming that there is no upward lift on the plane generated by its wings. Without such lift, the guideline slopes downward due to the weight of the plane. For purposes of significant figures, use 2.91 kg for the mass of the plane, 12.2 m for the length of the guideline, and 18.2 and 36.4 m/s for the speeds. (a) Number (b) Number Units UnitsAsap plzzzzA 944-kg automobile rounds a curve at a constant speed of 35 m/s, undergoing an acceleration of magnitude 1.9 m/s2 as it proceeds. What is the radius of the curve? (Answer in m.)
- On a typical road, the force of friction during a turn can be up to 195,000 N. If a car has a mass of 1050kg and makes a turn with a radius of 20.0m, how fast can it be going?A car of mass 622 kg is driving around a curve with a circular arc of radius 20 m. If the car drives at a speed of 12 m/s, what is the minimum value of the coefficient of friction between the car's tires and the road that will keep the car on the road?
