A driver is traveling 18.6 m/s when she sees a red light ahead. Her car is capable of decelerating at a rate of 3.55 m/s2 . How far from the beginning of the intersection will she be?
A driver is traveling at 30.0 m>s when he sees a moose crossing the road 80.0 m ahead. The moose becomes distracted and stops in the middle of the road. If the driver of the car slams on the brakes, what is the minimum constant acceleration he must undergo to stop short of the moose and avert an accident?
An ambulance driver traveling at 32.0 m/s (71.6 mph) honks his horn as he sees a motorist ahead on the highway traveling in the same direction. The motorist hears a frequency of 392 Hz and notices that his own speedometer reads 33.6 mph (15.0 m/s). Calculate the frequency that the ambulance driver hears. (Speed of sound is 340 m/s) (in Hz)
Suppose a car is traveling at +16.0 m/s, and the driver sees a traffic light turn red. After 0.225 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 8.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
Suppose a car is traveling at +17.6 m/s, and the driver sees a traffic light turn red. After 0.315 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 6.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
A driver is traveling at a speed of 70 km/h in car A when he looks down to text a friend that he is running late. Just before he looks down. he is 80 m from an intersection, and a bicydist B, traveling at a constant speed of 10m/s,s d= 40 m from that same intersection. The light turns red during the 3 s text, and when the driver looks up, he hits the brakes, causing a constant deceleration of...
A car is traveling at 20.0 m/s, and the driver sees a traffic light turn red. After 0.6 s (the reaction time), the driver applies the brakes, and the car accelerates at -6.1 m/s What is the stopping distance of the car, as measured from the point where the driver first sees the red light? ning: 1 of 1.00 uestion Answer Choose..

The speed limit in a school zone is 45 km/h. A driver traveling at this speed sees a child run onto the road 20 m ahead of his car. He applies the brakes, and the car decelerates at a uniform rate of 11.0 m/s2. If the driver's reaction time is 0.55 s, will the car stop before hitting the child?What is the stopping distance of the vehicle?
Please help me understand how to solve this problem 6) A driver is going 90 km/hr when he suddenly sees the stop light 40 m ahead. It takes the s before he applies the brakes. Once he does begin to brake, he decelerates at a rate of 10 m/s2 a) b) Does he stop on time? What would be the maximum speed at which the driver can go and NOT pass the stop light?
A 200-kg motorcycle and rider are traveling at 40 m/s. The rider notices a wreck ahead, applies the brakes, and manages to stop the car in 150 meters. Using work-energy, find the force of friction used to stop the car. (Pick the answer closest to the true value.) 12,500 newtons 3,375 newtons 387 newtons 1,067 newtons 2,280 newtons
