A body starts from rest and undergoes a constant acceleration of 4m/sec . Find it's displacement after 4seconds . Plz answer with explanation. |
|
Answer» ▪ Initial speed = ZERO (i.e. rest)▪ Acceleration = 4m/s²▪ Time INTERVAL = 4sTo Find :▪ Displacement of body after the given interval of time.Concept :☞ Since, acceleration has said to be constant throughout the motion, we can easily apply equation of kinematics to solve this type of questions.☞ SECOND equation of kinematics :☆ S = ut + (1/2)at²S denotes displacementu denotes initial velocityt denotes timea denotes accelerationCalculation :→ S = ut + (1/2)at²→ S = (0×4) + (1/2)(4)(4)²→ S = 0 + (2×16)→ S = 32M |
