For problems that involve an object accelerating along an inclined plane, how can the weight be used to determine the force component that causes motion? The weight is the full force that acts perpendicular to the surface of the ramp. The weight times the cosine of the ramp's angle is the force perpendicular to the ramp. The weight times the sine of the angle of the ramp acts down along the ramp. O The weight times the cosine of the angle of the ramp acts down along the ramp.

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?
