All objects moving in a circle experience centripetal force The form of centripetal force depend on the object in circular motion & the force causing the circular movement Which of the following describes the correct centripetal force acting on an object moving in a circle? The force of air resistance as a roller coaster performs a loop on a track
The force of friction as a car drives around a corner at constant speed
The force of gravity as a ball on a string is spun horizontaly in a circle
The force of inertia as a person spins on a ride at amusement park

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.

A1500 w electric heater is plugged into the outlet of a 120 v circuit that has a 20 a circuit breaker. you plug an electric hair dryer into the same outlet. the hair dryer has power settings of 600 w, 900 w , 1200 w, and 1500 w. you start with the hair dryer on the 600 w setting and increase the power setting until the circuit breaker trips. under what setting does the circuit breaker trip.
