PPSC LECTURER OF PHYSICS TEST NO. 45

1 / 25

A baseball is hit straight up and is caught by the catcher 2.0 s later. The maximum height of the ball during this interval is:

2 / 25

A vector of magnitude 20 is added to a vector of magnitude 25. The magnitude of this sum might be:

3 / 25

A projectile is shot vertically upward with a given initial velocity. It reaches a maximum height of 100 m. If, on a second shot, the initial velocity is doubled then the projectile will reach a maximum height of:

4 / 25

One object is thrown vertically upward with an initial velocity of 100 m/s and another object with an initial velocity of 10 m/s. The maximum height reached by the first object will be.......... that of the other:

5 / 25

An object dropped from the window of a tall building hits the ground in 12.0 s. If its acceleration is 9.80 m/s2, the height of the window above the ground is:

6 / 25

A certain vector in the xy plane has an x component of 4m and a y component of 10m. It is then rotated in the xy plane so its x component is doubled. Its new y component is about:

7 / 25

A stone is released from rest from the edge of a building roof 190 m above the ground. Neglecting air resistance, the speed of the stone, just before striking the ground, is:

8 / 25

Neglecting the effect of air resistance a stone dropped off a 175-m high building lands on the ground in:

9 / 25

Displacement can be obtained from:

10 / 25

If the magnitude of the sum of two vectors is less than the magnitude of either vector, then:

11 / 25

A stone is released from a balloon that is descending at a constant speed of 10 m/s. Neglecting air resistance, after 20 s the speed of the stone is:

12 / 25

As a rocket is accelerating vertically upward at 9.8 m/s2 near Earth’s surface, it releases a projectile. Immediately after release the acceleration (in m/s2) of the projectile is:

13 / 25

A stone is thrown vertically upward with an initial speed of 19.5 m/s. It will rise to a maximum height of:

14 / 25

A vector of magnitude 3 CANNOT be added to a vector of magnitude 4 so that the magnitude of the resultant is:

15 / 25

An object is released from rest. How far does it fall during the second second of its fall?

16 / 25

If the magnitude of the sum of two vectors is greater than the magnitude of either vector, then:

17 / 25

The coordinate-time graph of an object is a straight line with a positive slope. The object has:

18 / 25

A heavy ball falls freely, starting from rest. Between the third and fourth second of time it travels a distance of:

19 / 25

The area under a velocity-time graph represents:

20 / 25

An object has a constant acceleration of 3 m/s2. The coordinate versus time graph for this object has a slope:

21 / 25

A vector in the xy plane has a magnitude of 25m and an x component of 12m. The angle it makes with the positive x axis is:

22 / 25

An object is thrown straight down with an initial speed of 4 m/s from a window which is 8 m above the ground. The time it takes the object to reach the ground is:

23 / 25

Two vectors lie with their tails at the same point. When the angle between them is increased by 20◦ their scalar product has the same magnitude but changes from positive to negative. The original angle between them was:

24 / 25

We say that the displacement of a particle is a vector quantity. Our best justification for this assertion is:

25 / 25

Two vectors have magnitudes of 10m and 15 m. The angle between them when they are drawn with their tails at the same point is 65◦. The component of the longer vector along the line of the shorter is:
