1. Situation: You are to determine the duration of the yellow light at a highway intersection. Assume that cars will be approaching the intersection traveling at 70 mph, and that the reaction time of the driver is 2.5 sec and that cars achieve a deceleration of 1/8 of the gravitational acceleration. If g=32.2 fps?, a. How long must the traffic light remain yellow to allow drivers to come to stop before the traffic light turns red? b. What is the minimum distance of a car from the intersection when the light turns yellow to ensure that it comes to a full stop just before the intersection?

If no brakes are used immediately, an automobile with a starting velocity of 30 mph or 44 feet/s will collide with a person. If the driver is inebriated, he or she will be able to respond to the situation in three seconds. If the driver is not intoxicated, he or she can react for about 0.75 seconds. Determine the shortest stopping distance required for the driver (intoxicated, under influence of alcohol) to break on time if the automobile accelerates at -2 feet/s2.
A stone is thrown vertically upward from the ground with a velocity of 48.3ft/sec. One second later, another stone is thrown vertically upward with avelocity of 96.6 ft/sec. How far above the ground will the stones be at thesame level?The car is traveling at 48 km/h when the traffic light 90 mahead turns yellow. The driver takes one second to reactbefore he applies the brakes.(a) After he applies the brakes, what constant rate ofdeceleration will cause the car to come to a stop just asit reached the light?(b) How long does it take the car to travel the 90 m? Pls show complete handwritten solution, including all the pertinent solutions. Thanksss! ❤️
The 300N block rests upon a level plane for which the fk is 0.20. A force P = 100N, directed at 30° from the horizontal pulls the block and moves 80m starting from rest. If the 100N force is then removed, how much further will it travel? CHOICES: 48.803m 47.800m 40.780m none 40.078m

A sphere is fired downwards into a medium with an initial speed of 27 m/sec . If it experiences adeceleration of a= (-6t) m/sec2 where t is in seconds, determine the distance traveled before it stops.
If no brakes are used immediately, an automobile with a starting velocity of 30 mph or 44 feet/s will collide with a person. If the driver is inebriated, he or she will be able to respond to the situation in three seconds. If the driver is not intoxicated, he or she can react for about 0.75 seconds. Determine the shortest stopping distance required for the driver (normal, not under influence of alcohol) to break on time if the automobile accelerates at -2 feet/s2. *
Given that an object with initial velocity v0 has velocity v at a later time t given by v = v0 e −kt for some positive constant k ,→ calculate the position of the object as a function of time, and? [15] ,→ if the object start off from rest and k = 10 s−1 , determine the position of the object after
A cart has a mass of 1.5 kg. It is given some initial push toward a sensor and is slowed by a hanging mass which makes the cart turn around and speed up as it returns to its original position. This situation is illustrated in the attached image. If the acceleration towards the sensor is 0.5 m/s2 and the accaleration away from the sensor is 0.15 m/s2, a. draw the free body diagrams for the cart moving towards the sensor and away from the sensor. b. Write Newton's law for both situations and solve for the frictional force and for the force from the hanging mass.
