A 120-kg roller coaster cart is being tested on a new track, and a crash test dummy is loaded into it. The roller coaster starts from rest at point A which is 35m above the ground. The cart observed is to roll down the track to point B, which is 10 m above the ground. In your own words, what physics idea would you be able to use to predict how fast the cart is moving at point B?

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
