body starting from rest and moving with an uniform acceleration of 3 m/s²..What is its velocity after 15s?

□ The Final velocity of body = 45 m/s

Initial velocity of body = 0 m/s

Acceleration of body = 3 m/s²

Time taken by body = 15 sec

Final velocity of body = ?

Here in this question we are provided that a body is in rest so it's initial velocity will be 0 m/s (because from rest), Acceleration of body is 3 m/s², and Time taken is also given which is 15 sec.

 To calculate the Final velocity of body we'll use the first equation of motion which says v = u + at

Where,

From first equation of motion

Hence, the Final velocity of body is 45 m/s.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
