Question

A particle is moving with a velocity of 20 m per second after 5 second its velocity changes with an acceleration of 2 metre per second square find its velocity

Answer 1

Heya!!
--------

Given that ,

Initial velocity u = 20 m/s.

Time t= 5 seconds

Acceleration = 2m/s2.

Final velocity v =?

Using first equAtion of motion

V = u + AT

V = 20 + 2×5

V = 30 m/s

Answer 2

Answer:

Explanation:

Given that ,

Initial velocity u = 20 m/s.

Time t= 5 seconds

Acceleration = 2m/s2.

Final velocity v =?

Using first equAtion of motion

V = u + AT

V = 20 + 2×5

V = 30 m/s
