- write out functions for the displacement and velocity of each runnerYour answer is partially correct. 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 x₁ = 0 and the green car is at x§ = 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. (a) Number (b) Number 61.0 4.14 Red car Unit Unit km/h m/s^2 Green car xBy shooting water from its rear, a squid can provide itself with jet propulsion. Suppose a squid launches itself vertically upward from rest with constant upward acceleration for 0.890 s and travels a vertically upward distance of 2.72 m. The squid then turns off its jets and continues its flight in free fall. (a) What is the magnitude of the squid’s acceleration during the time it is jetting? (b) How long does it take the squid to reach its maximum height while in free-fall after jetting? (c) What maximum height did the squid attain?

- A man drives a car at v1= 54mi/h and suddenly notices a truck at a distance d= 13.5 m in front of him. That truck is moving in the same direction at a constant velocity v2= 34 mi/h. In order to not collide the person in the car must reduce their speed to v2 in a time interval, by slamming the brakes. the driver can give the car a maximum acceleration of ax. assume the acceleration is constant and the motion is in the positive direction. so that ax<0. 1) if the driver just barely avoids collision what is the final distance between the car and the truck? 2) write an expression for the distance Δx2 traveled by the truck in the time Δt, in terms of the quantities defined in the problem. 3) write an expression for the distance Δx1 traveled by the car in the time Δt, assuming the driver brakes as hard as they can. 4)Relate the total distance the car travels Δx1 to the distance the truck travels and the initial distance between them. 5)Find the acceleration of the car in terms of its…A private jet carrying Peter Parker takes off with a constant acceleration of 5m/s².
