Calculate its average speed in meters per second
Answer:
5.77 m/s
Explanation:
Speed= Distance/Time
Distance= 40+ half of 40= 40+20= 60 m
Time= 8.8+1.6=10.4 s
Average speed= 60/10.4=5.769230769 m/s
Approximately, the average speed is 5.77 m/s
Average acceleration: velocity/time
5/4= 1.25 m/s² Acceleration
Hope I helped :)
Gravitational potential energy is caused when an object is resting above the ground. It is released when the object is falling, not by burning substances.
