alexandr402 [8]

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
