... 5. What force is needed to turn a 750kg car around a corner with a radius of 12m if the car is going 43m/s? 6. The centripetal force required to turn a 17,000kg plane around a 450m arc is 54,0000N, how fast is the plane traveling? 7. A rock is on the end of a 3m string spinning at 25m/s. The centrip ...

1. When an object is moving - what effect will a balanced force have
... level street. The ball did not bump into any object, but it eventually came to a stop. How is this possible? A. Every moving object must come to a stop because energy cannot be destroyed. B. The unbalanced force that caused the ball to stop was friction. C. Newton's first law of motion only holds tr ...

Newton`s 2nd Law
... Normal force: Gravity pulls the object down the slope and into the slope. If we only consider the motion into the slope (perpendicular), the object has no perpendicular velocity. So the F= 0. Then the surface must push upward, equal and opposite to the perpendicular gravity component. Named the n ...
