The answer would be a=5 m/s^2
I hope this helps you, have a great day!
Answer: acceleration = slope graph velocity vs time
Explanation: if you have the graph of velocity vs time , the slope of that graph equals the acceleration of our object assuming constant acceleration...but remenber por a real object is really hard to keep constant acceleration
Answer:

Explanation:

Answer:
80 J
Explanation:
PE = mgh
PE = (4 kg)(9.8 m/s^2)(2 m)
PE = 78.4 J and with sig figs, it would be 80 J
