An object with mass m is spinning in uniform circular motion in a circle perpendicular to the ground with radius r at a circular velocity of 2 m/s. at the height of its spin, the forces acting on it, f, can be calculated by summing the force due to change in direction and the force due to gravity. the force due to gravity is the mass of the object multiplied by 9.8 m/s2s2. the force due to change in direction is the product of the square of the velocity of the object, the mass of the object, and the reciprocal of the radius. what is m in terms of r and f? a) f. r4+9.8rf. r4+9.8rb) f4r+9.8f4r+9.8c) f. r4r+9.8f. r4r+9.8d) 4r+9.8f4r+9.8fe) (f. r)−49.8r(f

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
