Question

The figure shows two boxes, with m_1 > m_2, that are on a level frictionless surface. We can apply a horizontal force F either toward the right-on m_1 or toward the left on m_2. The magnitude of the force that the boxes exert on each other is larger if F is applied toward the right. larger if F is applied toward the left. the same in either case. zero newtons in either case. A truck is using a hook to tow a car whose mass is one quarter that of the truck. If the force exerted y the truck on the car is 6000 N, then the force exerted by the car on the truck is 6000 N. 24000 N. 12000 N. 1500 N. We need to know if the car is accelerating to answer this question. A person is using a rope to lower a 5.0-N bucket into a well with a constant Speed of 2.0 m/s. What is the magnitude of the force exerted by the rope on the bucket? 0.00 N 10 N 5.0 N 2.0 N 49N A person who normally weighs 700 N is riding in a rather swift elevator that is moving at a constant speed of 9.8 m/s If this person is standing on a bathroom scale inside the elevator, what would the scale read? less than 700 N 700 N more than 700 N It could be more or less than 700 N, depending on whether the elevator is going up or down. What is the mass of an object, that experiences a gravitational force of 351 N near Earth, surface where g = 9.80 m/s^2 35.8 kg 35.1 kg 36.5 kg 37.2 kg If I weigh 876 N on Earth at a place where g = 9.80 m/s^2 and 5320 N on the surface of another planet, what is the acceleration due to gravity on that planet? 59.5 m/s^2 51.8 m/s^2 43.4 m/s^2 68.4 m/s^2

Explanation / Answer

here,

41)

from Newton's third law

c)

the force is same in either case

42)

the force exerted by the car on truck is same as the force exerted by truck on car

so the correct option is A) 6000 N

43)

as the speed is constant

the net force on the rope is zero

F - W = 0

F = W = 5 N

the force applied is C) 5 N

44)

as the elevator is moving with constant speed

the weight of the person is same as the original weight in elevator

so, B) 700 N is the correct answer
