In the figure here, a red car and a green car 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 = 225 m. If the red car has a constant velocity of 26.0 km/h, the cars pass each other at x = 44.1 m. On the other hand, if the red car has a constant velocity of 52.0 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? Include the signs.
In a marathon race Chad is out in front, running due north at a speed of 4.03 m/s. John is 97 m behind him, running due north at a speed of 4.70 m/s. How long does it take for John to pass Chad?
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 sperm whale can accelerate at about 0.140 m/s^2 when swimming on the surface of the ocean. How far will it travel if it starts at a speed of 1.20 m/s and accelerates to a speed of 2.5 m/s? Assume the whale travels in a straight line.
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.
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.

Express your answer to three significant figures and include the appropriate units.
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.
During the time interval 0 < t < 1, the velocity of an object as a function of time is v = 5 + 3t^2 + 2t^3. Knowing that the object follows a rectilinear trajectory, What is the correct expression for the acceleration?
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.
In the figure here, a red car and a green car 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 = 221 m. If the red car has a constant velocity of 29.0 km/h, the cars pass each other at x = 43.0 m. On the other hand, if the red car has a constant velocity of 58.0 km/h, they pass each other at x = 76.9 m. What are (a) the initial velocity (in km/h) and (b) the (constant) acceleration (in m/s2) of the green car? Include the signs. Please type answer no write by hend.
