A race car accelerates from rest at the starting line of a race to reach a speed of 30.0 km/h over a distance of 70.0 m and then continues with the same constant acceleration for another 11.0 s before slowing down to a speed of 25.0 km/h over a distance of 100. m. Another car begins to accelerate from rest at the start line and catches up to the first boat within 30.0 s. (a) Find the acceleration of the second car. (b) Find the time it takes the first car to cover the first 70 m. (c) Find the speed of the second car when it catches up to the first car there is nothing missing in this question that the question don't reject it
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

begins to accelerate from rest at the start line and catches up to the first boat within 30.0 s.
