Answer:
2m/s
Explanation:
Total Distance = 300m+200m = 500m
Total Time = 100s+150s = 250s
Average Speed = Total distance travelled/Total time taken
=500m/250s
=2m/s
Net force of the acceleration it’s increasing
Answer:
v = 0.5 m/s.
Explanation:
Total distance, d = 20 m + 20 m = 40 m
Total time taken, t = 30 s + 50 s = 80 s
The average speed of an object is the total distance divided by time taken. So,
So, the average speed of the object is 0.5 m/s.
There's a few differences. In a physical change the actual substance doesn't change, where in a chemical change with chemical reaction, a new substance is formed. Physical change can be reversed, and chemical change can't.
