Question

find the displacement in the 3rd second.Of a car has initial velocity of 20m/s and acceleration of 3m/s^2.​

Answer 1

Answer:

how we can change the uniform velocity of a moving object to non uniform velocity

Answer 2

Answer:

u=20m/s

a=3m/s^2

t=3s

S=ut+1/2at^2

=20×3+1/2×3×3×3

=60+1/2×27

=60+27/2

=120+27/2

=147/2

=73.5
