Q6)A fish takes the bait and pulls on the line with a force of 2.4 N . The fishing reel, which has a friction clutch that exerts a restraining torque of 0.042 N?m , is a cylinder of radius 0.050 m and mass 0.89 kg.What is the angular acceleration of the fishing reel? What is the angular acceleration of the fishing reel?

Q7) Two astronauts on opposite ends of a spaceship are comparing lunches. One has an apple, the other has an orange. They decide to trade. Astronaut 1 tosses the 0.130 kg apple toward astronaut 2 with a speed of vi,1 = 1.05 m/s . The 0.150 kg orange is tossed from astronaut 2 to astronaut 1 with a speed of 1.19 m/s . Unfortunately, the fruits collide, sending the orange off with a speed of 1.03 m/s in the negative ydirection. What are the final speed and direction of the apple in this case?

Explanation / Answer

Solving 1st question

Assuming cylinder is solid cylinder

I=moment of inertia of reel=mr^2/2=1.1125*10^(-3) kgm^2

T=net torque=-0.042+(2.4*0.05)=0.078 Nm

angular acceleration=T/I=70.1 rad/s^2
