Vic = 40 m/s Vy=-10 m/s ac = -6 m/s2 170 m 1. Chris is driving at the initial speed of 40 m/s. Then he sees a tumbleweed approaching him at 10 m/s, 170 m away from him. He immediately steps on the brake, decelerating at ac = -6 m/s? How long will it take for the car to collide with the tumbleweed?

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...

You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop? A rock is tossed straight up with...
