1.	A body moving along a straight line at 20 M/s undergoes an acceleration of 4m/s^2 what is its speed after 2 second?
Answer» initial SPEED (u)=20 final SPEEED(V)=v a=4 using first LAW of motion v=u+at v=20+4x2 v=28m/s speed will be 28m/s

A body moving along a straight line at 20 M/s undergoes an acceleration of 4m/s^2 what is its speed after 2 second?

Answer»

initial SPEED (u)=20

final SPEEED(V)=v

a=4

using first LAW of motion

v=u+at

v=20+4x2

v=28m/s

speed will be 28m/s
