is upcat structured like this?
i generate a physics question sa ai, and this is what it turns out.
Question 1
A construction worker holds a heavy 20-kg toolbox at a constant height of 1.5 meters above the ground while waiting for a hoist for exactly 5 minutes. How much work is done by the worker on the toolbox during this time interval?
A) 0 J
B) 30 J
C) 300 J
D) 90,000 J
⸻
Question 2
An object moves along the x-axis under the influence of a varying force F, as shown in the graph below.
What is the net work done on the object from x = 0 m to x = 6 m?
A) 32 J
B) 24 J
C) 16 J
D) 8 J
⸻
Question 3
A constant horizontal pulling force F moves a crate across a rough floor at a constant speed v. If the pulling force is doubled to 2F while the surface properties remain the same, what happens next?
A) It continues moving at a constant speed of 2v.
B) It accelerates continuously with a constant net force equal to F.
C) It moves with a constantly increasing acceleration.
D) It stops moving because of increased kinetic friction.
⸻
Question 4
Two identical shopping carts, Cart X and Cart Y, are pushed from rest across a frictionless floor. The net force applied to Cart X is twice that applied to Cart Y (Fx = 2Fy).
If both carts are pushed over the same distance, what is the ratio of their final kinetic energies (KEx : KEy)?
A) 1 : 2
B) 1 : 1
C) 2 : 1
D) 4 : 1
⸻
Question 5
Using the same carts from Question 4, Cart X and Cart Y are pushed from rest with forces such that Fx = 2Fy, but this time they are pushed for the same amount of time (tx = ty).
What is the ratio of their final kinetic energies (KEx : KEy)?
A) 1 : 2
B) 2 : 1
C) 4 : 1
D) 8 : 1
ganito ba talaga sya kahirap at kalalim??😭 i can answer maroon blue book physics question and i can understand it clearly pero ito?? it was difficult bruh… can someone help me out here plsss
