Question

what will be the final velocity of a car if it starts from rest and accelerates at 8m/s after 4 seconds​

Answer 1

Explanation:

intial velocity (u) =0

final velocity (v) = 8 m/s

time = 4s

accerlation =v-u/t =8-0/4 =2 m/s ²

Answer 2

Answer:

32

Explanation:

v=u+at

where, u is initial velocity

v is the final velocity

a is acceleration

t is the time period

since the car starts from rest u= 0

therefore,v=0+8*4

v=32
