PPSC LECTURER OF PHYSICS TEST NO. 49

1 / 25

A 400-N steel ball is suspended by a light rope from the ceiling. The tension in the rope is:

2 / 25

A 25-N crate is held at rest on a frictionless incline by a force that is parallel to the incline. If the incline is 25◦ above the horizontal the magnitude of the applied force is:

3 / 25

A 32-N force, parallel to the incline, is required to push a certain crate at constant velocity up a frictionless incline that is 30◦ above the horizontal. The mass of the crate is:

4 / 25

A 5-kg concrete block is lowered with a downward acceleration of 2.8m/s2 by means of a rope. The force of the block on the rope is:

5 / 25

When a 40-N force, parallel to the incline and directed up the incline, is applied to a crate on a frictionless incline that is 30◦ above the horizontal, the acceleration of the crate is 2.0m/s2, up the incline. The mass of the crate is:

6 / 25

A block slides down a frictionless plane that makes an angle of 30◦ with the horizontal. The acceleration of the block is:

7 / 25

A 5-kg concrete block is lowered with a downward acceleration of 2.8m/s2 by means of a rope. The force of the block on Earth is:

8 / 25

A man weighing 700 Nb is in an elevator that is accelerating upward at 4m/s2. The force exerted on him by the elevator floor is:

9 / 25

A book rests on a table, exerting a downward force on the table. The reaction to this force is:

10 / 25

A 25-N crate slides down a frictionless incline that is 25◦ above the horizontal. The magnitude of the normal force of the incline on the crate is:

11 / 25

You stand on a spring scale on the floor of an elevator. Of the following, the scale shows the highest reading when the elevator:

12 / 25

A crane operator lowers a 16, 000-N steel ball with a downward acceleration of 3m/s2. The tension force of the cable is:

13 / 25

A 25-N crate is held at rest on a frictionless incline by a force that is parallel to the incline. If the incline is 25◦ above the horizontal the magnitude of the normal force of the incline on the crate is:

14 / 25

Two forces are applied to a 5.0-kg crate; one is 6.0N to the north and the other is 8.0N to the west. The magnitude of the acceleration of the crate is:

15 / 25

A lead block is suspended from your hand by a string. The reaction to the force of gravity on the block is the force exerted by:

16 / 25

You stand on a spring scale on the floor of an elevator. Of the following, the scale shows the highest reading when the elevator:

17 / 25

The “reaction” force does not cancel the “action” force because:

18 / 25

A car moves horizontally with a constant acceleration of 3m/s2. A ball is suspended by a string from the ceiling of the car. The ball does not swing, being at rest with respect to the car. What angle does the string make with the vertical?

19 / 25

When a 25-kg crate is pushed across a frictionless horizontal floor with a force of 200 N, directed 20◦ below the horizontal, the magnitude of the normal force of the floor on the crate is:

20 / 25

A sled is on an icy (frictionless) slope that is 30◦ above the horizontal. When a 40-N force, parallel to the incline and directed up the incline, is applied to the sled, the acceleration of the sled is 2.0m/s2, down the incline. The mass of the sled is:

21 / 25
