Problem 3 (30 points) Three cars are driving at 15 m/s along the road shown in...
Two cars are driving at the same constant speed on a straight road, with car 1 in front of car 2. Car 1 suddenly starts to brake with constant acceleration and stops in 10 m. At the instant car 1 comes to a stop, car 2 begins to brake with the same acceleration. It comes to a halt just as it reaches the back of car 1. What was the separation between the cars before they starting braking?
020 (part 1 of 3) 10.0 points You are driving at the speed of 34.8 m/s (77.862 mph) when suddenly the car in front of you (previously traveling at the same speed) brakes and begins to slow down with the largest deceleration possible without skid- ding. Considering an average human reaction, you press your brakes 0.576 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.722 between both...
An automobile is moving at speed of 2.00 m/s along a circular road of radius 20 m. A) Find the time it takes to make one full circle when the car is still moving at constant speed. (1P) B) Find the car radial acceleration during this time. (1P) Then its speed starts increasing at a rate of 0.600 m/s2 while it stays on the same road. C)How long would it take for the car to make one full turn from...
Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...
7. A highway curve with a radius of R metres is banked so that cars moving at v m/s around the curve do not have to rely on friction when taking the turn. IWPS 7. No.4] 7.1 Show (from first principles) that the angle, 6, at which, the road should be banked is given by: 0 arctan 7.2 A particular banked highway curve with a radius of 200 m is designed for traffic moving at 60 km/h. On a rainy...
Full Solution Problem for Chapter 06 (FS06)-Using Generalized Momentum-Impulse equation driving 20 m/s when it sees a deer (at rest in the road). The driver of the car hits the brakes, but it's too late- he hits the deer. The deer sticks to the car (sorry, deerl) and they skid forward as the car br has a mass of 500 kg and the deer has a mass between the car's tires and the road is 0.&. (Friction is much smaller...
Please help answer all of question 6, thanks! Rotational Dynamics Assignment (200 Points) • Due Friday, July 31 at 5:00 pm Equations are in a separate document entitled “Equations for Rotational Dynamics Assignment” • Moments of inertia formulas are provided on the last page of this document • Show all of your work when solving equations. It is not sufficient to merely have a correct numerical answer. You need to have used legitimate equations and algebra. You also need to...
