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
