Answer:
answer is option D ) 34m/s
Step-by-step explanation:
initial velocity (u)=14m/s
time of acceleration (t)=5s
acceleration (a)=4m/s^2
final velocity (V)= ?
we will use the equation:
V=u+at
which comes from a= (v-u)/t
so
putting the values
V= 14+(4)(5)
v = 14+20
v = 34
hence the option D is correct
