Answer:
6.7 /s.
Step-by-step explanation:
Initial velocity = u m/s
From the question, final velocity, v = - 2u m/s
Note - (the minus sign indicates that the direction was reversed and doubled)
t = 0.45
From equation of motion,
v = u + at
Acceleration, a = (v - u)/t
= (-2u - u)/0.45
= - 3u/0.45
Acceleration, a/Original speed, u = 3/0.45
= 6.7 /s
Answer:
I'm not sure if that's what is meant cuz the text is a little ambiguous

Eva because 3:2 = 9:6 because when they multiply by 3 on each ratio
The answer is 3 of each. 3X7=21; 14X3=42, and 42+21= 63.
