Himal kharel said:Four people(K,L,M,N) are on four sides of a square having side of length 15m. K follows L. L follows M. M follows N. N follows K. they all have speed of 1 m/s. at what time they meet.
I don't know anything what to do.
Kinematics is a branch of physics that studies the motion of objects without considering the forces that cause the motion.
The three main quantities studied in kinematics are position, velocity, and acceleration.
Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that measures both the speed and direction of an object's motion.
Average velocity is the total displacement of an object divided by the total time taken, while instantaneous velocity is the velocity at a specific moment in time.
Acceleration is the rate of change of velocity with respect to time. This means that an object with a changing velocity will also have an acceleration.
