Question

If u= 10 m/s,v=20 m/s,t=5 s,calculate the acceleration​

Answer 1

Answer:

v

i

=10 m/s and v

f

=20 m/s

Acceleration of the body =

5

20−10

m/s

2

a=2 m/s

2

Velocity of the body at t=−3 sec

v=u+at

v=10−2×3

v=4 m/s

Answer 2

Answer:

acceleration is 2

a= v-u / t...

a= 20-10 / 5 ...

a= 10 /5...

therefore a= 2 m/ s square
