Question

(a) A car starts from rest with
a constant acceleration of 1 m/s2
Calculate its velocity after 20 second.​

Answer 1

Answer:

Initial velocity 'u' = 0m/s

acceleration 'a' = 1 m/s^2

time 't' = 20 sec

Therefore, final velocity 'v' = ?

so,

a = v-u/t

=> 1 = v - 0/ 20

=> v = 1 x 20 = 20

therefore, final vel. after 20sec will be 20m/s
