Answer: 0.067 meters/sec²
Explanation:
First we have to convert speeds to meters per second since time is in seconds.:
We have to multiply speeds by 1min/60sec
Beginning speed (70m/min)x(1min/60sec) = 70/60 m/s
Final speed (106m/min)x(1min/60sec) = 106/60 m/s
Acceleration = (Final speed - Beginning speed) ÷ time
Acceleration = (106/60 - 70/60)m/s ÷ 9s
Acceleration = (36/60)m/s ÷ 9s
Acceleration = 36m/60·9s²
Acceleration = 36m/540s²
Acceleration ≅ 0.067 m/s²
Answer: Acceleration ≅ 0.067 meters/sec²
