dot over the first 0.6 s? Give your answer to 1 decimal place in rad/s

Question 1 b)

Giovanni

decides to turn around by 180° but continues to

push with the same magnitude of force as before. What is the net torque on the

merry-go-round now?

Question 1 a)

Suzanne and Giovanni are pushing a merry-go-round with a

diameter of 5 metres. They push in the directions shown in the figure below:

a)    

If Suzanne pushes with a force of 41.5 N and Giovanni

pushes with a force of 35.0 N, what is the net torque on the merry-go-round? Take the anticlockwise direction as positive. Give

your answer to 2 decimal places in Newton. Write your answer without units i.e.,

12.61 N as 12.61.
