Average acceleration is how much the car increases (on average) per second. So, since it increases by 30 m/s in 8 s, then dividing 30 by 8 will give you an average acceleration of 3.75 m/s^2 (remember that acceleration is ever increasing, so the unit is s^2, not just s)
Hope this helps!
Answer:
1. B- kinetic to gravitational potential energy
2. A-gravitational to kinetic energy
Explanation:
When the train goes up the hill, the kinetic energy decreases (the speed decreased) due to the pull of gravity.
When the train goes down the hill, the speed increases (kinetic energy increases) and since the object is coming downwards the gravitational potential energy decreases
The magnitude of a vector is the square root of its components squared. When you square a negative number, you will always get a positive number. Its like speed of your car. It will always be positive (or 0) whether you are moving forward or you are in reverse gear or stationary.
