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), if any, do the cars pass each other? (d) What are their locations at that time?

Terry has a new toy car that rolls on a bright orange track. He's rolling the car back and forth. During a certain interval of time, the motion of the car can be mathematically described with this equation: x(t) = 1.50 + 3.50t - 1.50 t^2 + 0.500 t^3 For t = 2.31, answer the three questions below. What is the position of the car? x = What is the velocity of the car? V = What is the...

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...

A "rocket car" is launched along a long straight track at t = 0 s. It moves with constant acceleration = 1.3 m/s^2. At t = 2.5 s, a second car is launched with constant acceleration a_2 = 7.8 m/s^2. At what time does the second car catch up with the first one? Express your answer using two significant figures. How far have the cars traveled when the second passes the first? Express your answer using two significant figures.
