A Ferris wheel with a radius of 9.8 m rotates at a constant rate, completing one revolution every 37 s. Suppose the Ferris wheel begins to decelerate at the rate of 0.19 rad/s2 when the 60-kg passenger is at the top of the wheel. Find the magnitude of the net torque on the passenger at that time.

Consider a system to be two train cars traveling toward each other. what is the total momentum of the system before the train cars collide?   kg • what must the total momentum of the system be after the train cars collide?   kg •  

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
