8). (15 points) Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.50 m/s2. This car moves toward a second car that is 32.0 m away. The second car is moving away from the first car and is traveling at a constant speed of 4.50 m/s. a) Where will the cars collide? b) How long will it take for the cars to collide?
A 1000 kg weather rocket is launched straight up.The rocket motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 6200 m. You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16s? What is the rocket's speed as it passes through acloud 6200 m above the ground?
A car moving at 90 km/h passes a 1.21 km -long train traveling in the same direction on a track that is parallel to the road. Part A If the speed of the train is 71 km/h , how long does it take the car to pass the train? Express your answer using two significant figures. Part B How far will the car have traveled in this time? Express your answer using two significant figures. Part C If the car...
7. Two train cars are on a straight, horizontal track. The car A starts at rest and is put in motion with a constant acceleration of 2.00 m/s2. This car A moves toward the car B that is 25.0 m away. The car B is moving in same direction as car A with an initial velocity of 4.5 m/s and is traveling with a constant acceleration of -1.50 m/s2 a) Where will the cars collide? b) How long will it...

At t = 0, one toy car is set rolling on a straight track with initial position 17.0 cm, initial velocity -4.1 cm/s, and constant acceleration 2.90 cm/s2. At the same moment, another toy car is set rolling on an adjacent track with initial position 9.0 cm, initial velocity 6.00 cm/s, and constant zero acceleration. (a) At what time, if any, do the two cars have equal speeds? (b) What are their speeds at that time? (c) At what time(s),...
8. Atoy car moving along a straight track has an acceleration given by a = -2.00 m/s? + (3.00 m/s)t and passes through the same point at t = 0 and at t = 4.00 s. a. Find the car's velocity at t = 4.00 s. b. Make two stacked sketches of the velocity and acceleration as functions of time using the same time scale on both so that the two can be compared. c. During what time period(s) is...
