Question

if a car travel 21s with a velocity changes from 70 M per second to 10 metre per second in 20 second find acceleration​

Answer 1

Answer:

When t=1, the velocity of the particle is 4+2=6 m/s.

When t=1, the velocity of the particle is 4+2=6 m/s.When t=2, the velocity of the particle is 4+2×2=8 m/s.

When t=1, the velocity of the particle is 4+2=6 m/s.When t=2, the velocity of the particle is 4+2×2=8 m/s.After t seconds, the velocity of the particle is 4+2t m/s.

Hope this will help you

Have a beteaous day ahead buddy
