Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

3. A group of young explorers invent a scheme to pull a ore car out of an sloping mine shaft at an abandoned mine. The idea is to fill a bucket of water attached to the ore- ar until is starts to move up the slope. If the ore car has a mass of 80 kg and the track is inclined at 15-degrees above the horizontal, what mass of water would be required to start the ore car moving if friction were negligible? If the frictional coefficient between the car and the track was 0.20, what mass of water would be needed to start the car moving? With friction present, suppose water is added until the car is just about to move. Now add an additional 4 kg of water with the car's wheels locked. When the wheels are unlocked how long will it take the car to move 34 meters up the track? ORE CAR -of a WATER BUCKET
