a bus moving along straight line at 20m/a undergoes an acceleration of 4m/s*2.after 2 sec its speed will be...
answer step by step​

Answer 1

Answer:

INITIAL VELOCITY OF BUS IS 20 M/S

ACCELERATION =4M/S^2

TIME TAKEN=2 SECONDS

FINAL VELOCITY =V

NOW,

v=u+at

=>v=20+8=28 m/s

HENCE FINAL VELOCITY WILL BE 28 M/S
