I was working over some problems from my physics textbook, and I came across this one, it involves circular movement:
A car with the mass of 1t is moving over a hill with the velocity of 20 m/s. The radius of the hill (which can be viewed as a half-circle) is 100m.
When it comes to the top of the hill, with what force does it act upon the hill?
The correct answer is, apparently, 6kN. How do I solve this?
The situation can be illustrated like this I guess:
