bearhunter [10]

Answer:

t=L/V_1

Explanation:

<u>solution:</u>

Let E be an observer, and B a second observer traveling with velocity V_{BE}  as measured by E. If E measures the velocity of an object A as V_{AE}  then B will measure A velocity as

V_{AB} = V_{AE} -  V_{BE}  

Applied here,

the walkway (W) and the man (M) are moving relative to Earth (E}, the velocity of the man relative to the moving walkway is

V_{MW} = V_{ME} -  V_{WE}  

V_1=V_{WE},

V_2=V_{MW}

The time required for the woman, traveling at constant speed V_1 relative to the ground, to travel distance L relative to the ground is :

t=L/V_1

Answer:

The work done is 32.2kJ

Explanation:

Work is defined as the product of force and distance moved in the direction of application of force.

W= F*S

Given Data

distance S= 230m

force F= 140 N

Mass of car m= 1140 kg

Applying the formula for work done we have

W=  140*230\\W= 32200 J\\W= 32.2kJ

The work done by pushing the car for a distance of 230m is 32.2kJ
