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.
need help with ANALYZE PART A AND B and FINALIZE EXPLORE A car is moving with constant acceleration along a straight road (A) Determine how the velocity and the displacement of the car vary with time if the car is initialy moving to the right with a speed of 9.0 m/s and has an acceleration to the right of 1.7 m/s (B) Determine the velocity as a function of time when the velocity is instead initially to the right and...
A particle is moving along a straight path such that the acceleration a = (3v2-2) m/s2, where v is in m/s. If v = 15 m/s when s = 0 and t = 0, please determine the particle’s position, velocity, and acceleration as functions of time.

A red car and a green car are traveling along a straight road in the same direction. The red car's position is given by x(t)=t3 and the green car is accelerating at a constant rate. At time t = 0, the green car is 132 m ahead of the red car. At t = 2 s, the red car reaches the same speed as the green car, and at t = 6 s, the red car catches up to 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...
