Solve all the following questions with out skipping any questions with step by step solution.

1) A top-loading washing machine has a cylindrical basket that rotates about a vertical axis. The basket of one such machine starts from rest and reaches an angular speed of 4.0 rev/s in 7.0 s. The lid of the machine is then opened, which turns off the machine, and the basket slows to rest in 9.0 s. Through how many revolutions does the basket turn during this 16 s interval? Assume constant angular acceleration while it is starting and stopping.

------------

2) An electric drill starts from rest and undergoes uniform angular acceleration for a period of 0.100 s until it turns at a rate of 2.90 10⁴ rev/min.

(a)What is the drill's angular acceleration (in rad/s²)? (Enter the magnitude.)

------------ rad/s²

b) What is the angle (in radians) through which the drill rotates during this period? (Enter the magnitude.)

----------- rad

3)

(a)Find the magnitude of the gravitational force (in N) between a planet with mass 8.25 10²⁴ kg and its moon, with mass 2.85 10²² kg, if the average distance between their centers is 2.40 10⁸ m.

---------- N

b) What is the moon's acceleration (in m/s²) toward the planet? (Enter the magnitude.)

---------- m/s²

c) What is the planet's acceleration (in m/s²) toward the moon? (Enter the magnitude.)

---------- m/s²

4) Two objects attract each other with a gravitational force of magnitude9.70*10^-9N when separated by19.6cm.If the total mass of the objects is5.02kg,what is the mass of each?

heavier mass ---------- kg

lighter mass ------------ kg
