Question

The velocity of a body moving with an initial velocity of 20 m/s and having an acceleration of 4m/s2 after 2 sec will be

Answer 1

Answer:

Hey see what is given initial velocity v and accelataration is given time is given you have to find u

Explanation:

formula a=v-u /t

4=20-u/2

u=20+4/2

u= 24/2

u = 14 m/s 2 --》》》 ans

Answer 2

Answer:

v= 28

Explanation:

a=v-u/t

(a=4 , u=20m/s , t= 2s). ( given )

4= v-20/2

8=v-20

v=28
