A car is 126 m from a stop sign and traveling toward the sign at 29 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
A blue car is moving at a constant speed of 70 m/s when it passes signage with a police officer beside it. Due to the car's over speeding, the police officer chases it with a constant acceleration of 4 m/s2, one second after the car passes the signage. How long does it the police officer to overtake the truck?
An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?
In a location where the train tracks run parallel to a road, a high-speed train traveling at 100 m/s passes a car traveling at 20 m/s. How long does it take for the train to be 240 m ahead of the car?
Mikail is sailing a boat in the local lake. Starting from rest near the shore, he accelerates uniformly at 0.3101 m/s/s. After 22 seconds, how far is he from the shore?
A commuter is driving a car along a straight road at a constant speed of 15.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 3.50 m/s2 to overtake her. Assume that the officer maintains this acceleration. What If? Determine the answers to parts (a) through (c) of the problem, if instead of accelerating at the same instant the car passes him, the officer instead begins his acceleration 1.00 s after the car passes him. (Enter the time in s, speed in m/s, and displacement in m.) time s speed m/s displacement m
An ambulance driver is rushing a patient to the hospital. While traveling at 71.1 km/h, she notices the traffic light at the upcoming intersection has turned yellow. To reach the intersection before the light turns red, she must travel 52 m in 2.17 seconds. What is the magnitude of the minimum acceleration, in m/s2, required to reach the intersection before the light turns red?
A police car is traveling at a velocity of 17.0 m/s due north, when a car zooms by at a constant velocity of 42.0 m/s due north. After a reaction time 0.300 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s^2. Including the reaction time, how long does it take for the police car to catch up with the speeder?
Car A is parked along the northbound lane of a highway, and car B is traveling in the southbound lane at a constant speed of 60 mi/h. At t=0, A starts and accelerates at a constant rate a A , while at t= 5 s, B begins to slow down with a constant deceleration of magnitude a A 6. Knowing that when the cars pass each other x = 294 ft and VA = VB , determine (a) the acceleration aA,(b) when the vehicles pass each other, (c) the distance d between the vehicles at t=0.
A police car is traveling at a velocity of 16.0 m/s due north, when a car zooms by at a constant speed of 50 m/s due north. After a reaction time of 0.700 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s2. Including the reaction time, how long does it take for the police car to catch up with the speeder?
Two cars leave from an intersection at the same time. Car A travels south at 80 km/h, while car B travels east at 60 km/h. At what rate is the distance between the cars increasing one hour later?
A jetliner traveling north is landing with a speed of 74 m/s. Once the jet touches down, it has 755 m of runway which reduced its speed to 11.1 m/s. What is the average acceleration (magnitude & direction) of the jet during landing?
