The first, third, fourth, fifth and sixth
Answer:
0.90m/s²
Explanation:
Given parameters:
Initial speed = 6miles/hr
Final speed = 12miles/hr
Time taken = 3 seconds
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time. It is mathematically given as:
Acceleration = 
We need to convert miles/hr to meters/seconds
Initial speed = 6 x 
x 
x 
= 2.68m/s
Final speed = 12 x 
= 5.37m/s
Acceleration = 
= 0.90m/s²
