A girl starts her car and accelerates uniformly to 7m/s in a distance of 14m. Calculate the acceleration of the girl and the time taken by her to travel the distance​.

u = 0  

v= 7m/s  

s=14m  

From the relation,  

v²=u²+2as  

47=0+2×a×14  

a= 2×14/27  

a=1.03703704  

time taken  

v=u+at  

7=0+1.03703704×t

t=6.74999764s

Hope it helps

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
