A red car and a green car, identical except for the colour, move toward each other in adjacent lanes and parallel to an x-axis. At time t = 0, the red car is at Xr = 0 and the green car is at Xg = 220 m. If the red car has a constant velocity of 20 km/h, the cars pass each other at x = 44.5 m, and if it has a constant velocity of 40 km/h, they pass each other at x = 76.6 m. What are (a) the initial velocity and (b) the constant acceleration of the green car?

A particle that moves along the x-axis has its position given by x=54t – 2t^3 m. At the instant t = 3.0 s, the particle speed is zero. Which of the following statements is correct? a)The particle remains at rest after t = 3.0 s b)The particle does not accelerate any more after t s 3.0 s c)The particle can be in positions x < 0 m only when t < 0 s d)All of the above are correct e)None of the above is correct
A group of students celebrate their first year of medical school with a hot-air balloon ride, which is rising upward with a constant speed of 3.0 m/s. When the balloon is 3.50 m above the ground, one of the students who is taking a selfie with the other students accidentally drops her smart phone over the side of the balloon (fortunately with a OtterBox case). With what speed would the phone hit the ground in m/s? Note that the displacement of the phone dropping 3.50 m would be - 3.50 m. For the same situation as Question 9, how long in seconds would the smart phone be in the air before it hits the ground?
. A hot-air balloon is drifting straight downward with a constant speed of 2.40 m/s. When the balloon is7.63 m above the ground, the balloonist decides to drop one of the ballast sandbags to the ground below.How much time elapses before the sandbag hits the ground?

A rail gun shoots a projectile in a straight line with acceleration aa and in time tt as defined by the equation a(t)=3−2t. If the projectile from the launcher reaches a velocity of 10 at t=1 and if s(t) is the distance of the projectile from the rail gun at time t, find s(5)−s(1)
Runner A is initially 6.0 mi west of a flagpole and is running with a constant velocity of 7.0 mi/h due east. Runner B is initially 5.0 mi east of the flagpole and is running with a constant velocity of 4.0 mi/h due west. How far are the runners from the flagpole when they meet? The answer has to be in miles.
On a one lane road, a person driving a car at v1 = 58 mi/h suddenly notices a truck 1.1 mi in front of him. That truck is moving in the same direction at v2 = 35 mi/h. In order to avoid a collision, the person has to reduce the speed of his car to v2 during time interval Δt. The smallest magnitude of acceleration required for the car to avoid a collision is a. During this problem, assume the direction of motion of the car is the positive direction. 1. Use the expressions you entered in parts (c) and (f) and enter an expression for a in terms of d, v1, and v2. a = ( v2 - v1 )/Δt Δt = ( 2 ) ( d )/( v1 - v2 ) 2. Calculate the value of a in meters per second squared.
Car A moves to the right with velocity 12 m/s. As soon as it reachesCar B, Car A accelerates at 3.00 m/s^2 . At the same time, starting from rest, Car B also accelerates at 5.00 m/s^2. How far will Car B have to travel to catch up with Car A?
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?
Recall the famous experiment of Galileo Galilei on top of the leaning tower of Pisa? If he accidentally dropped one stone 1.0 s ahead of the other, with what initial velocity (in m/s) must the second stone would have to be thrown if the two stones would hit the ground at the same time? Note: The tower is 54 m high.
As an airplane is taking off at an airport its position is closely monitored by radar. The following three positions are measured with their corresponding times: x1 = 145.50 m at t1 = 3.10 s, x2 = 185.00 m at t2 = 3.60 s, x3 = 229.50 m at t3 = 4.10 s. What is the acceleration of the airplane at t2 = 3.60 s? (Assume that the acceleration of the airplane is constant.) What is the average velocity of the airplane during the first time interval? What is the average velocity of the airplane during the second time interval?
In a friendly game of chicken, Car A has a starting distance of 160m in front of Car B. Both cars start with the same speed of 100 km/h, and both cars accelerate at constant rates. Knowing that Car B accelerates at 4.25 m/s^2. And car A accelerates at 4.00 m/s^2 . Determine the position in meters, that they crash.
