Question

The velocity of a body moving at an initial speed of 20 m/s and having an acceleration of
4 m/s after 2 s will be​

Answer 1

Answer:

By the first eqn of motion

v=u+at Put the given values

v=20+2×4

u=28 m/sec

Answer 2

✰ Given :

• ➝ Initial Speed of Body = 20 m/s

• ➝ Acceleration of Body = 4 m/s

• ➝ Time taken = 2 S

✰ To Find :

• ➲ Final Velocity of Body

✰ Solution :

• ➣ FORMULA :- V = U + at

• ➣ V = 20 + 4 × 2

• ➣ V = 20 + 8 m/s

• ➣ V = 28 m/s

★ Therefore :

• ➦ Final Velocity of body is 28 m/s
