V. DISPLACEMENT, VELOCITY AND ACCELERATION 19. A boy from rest started jogging with an acceleration of 2 m/s2 from t=0 to t=10s. The boy maintained that acceleration for the next 5 seconds then came to stop at t=22s. Draw the acceleration-time graph then find the velocity of the boy. *Answer with the magnitude of the velocity. 20. A car is travelling with a constant speed of 60 km/h for about 10 seconds then it came to stop at t=18s. Draw the velocity-time graph then find the displacement of the car, in meters, given that it is towards the same direction as the initial direction of the car. *Answer with the magnitude of the displacement. • Pls see the pictures • PLS WRITE THE SOLUTION PLS

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.
