Question

a body starts from rest and Acquires a velocity of 4 m/s .during a displacement of magnitude 4m . its acceleration is

Answer 1

Firstly we have to find time
From formula displacement=velocity/time
Therefore 4m=4m/s/time
Hence time =4/4=1 second
Now find acceleration from formula
Acceleration=velocity/time
Hence acceleration=4m/s/1s=4metres answer
