The man tries to reposition the 50 kg refrigerator in his kitchen by pushing it from rest with a force P = 170 N, inclined 30° from the horizontal at 1.60 m from the floor. The coefficient of non-sliding friction between the floor and the refrigerator is μs = 0.40. After pushing, the refrigerator started to tip. Which of the following quantities is ZERO at the instant described in the problem? a. friction at A b. body's angular acceleration c. body's angular velocity d. the acceleration of mass center G Which of the following values is closest to the magnitude of the angular acceleration of the refrigerator? a. 7.57 rad/s^2 b. 2.50 rad/s^2 c. 1.892 rad/s^2 d. 1.877 rad/s^2

Question
The man tries to reposition the 50 kg refrigerator in his kitchen by pushing it from rest with a force P = 170 N, inclined 30° from the horizontal at 1.60 m from the floor. The coefficient of non-sliding friction between the floor and the refrigerator is μs = 0.40.
After pushing, the refrigerator started to tip.
Which of the following quantities is ZERO at the instant described in the problem?
a. friction at A
b. body's angular acceleration

d. the acceleration of mass center G
Which of the following values is closest to the magnitude of the angular acceleration of the refrigerator?
a. 7.57 rad/s^2
b. 2.50 rad/s^2
c. 1.892 rad/s^2
d. 1.877 rad/s^2
