A747 jumbo jet of mass 300,000 kg accelerates down the runway at 4 m/s2 . what must be the force generated by each of its four engines

300000 N

Explanation:

We are given that

Mass of jumbo jet=300,000kg

Acceleration of jet=

We have to find the force generated by each of its four engines.

We know that

Force,F =ma

Total force exert by four engines=4F

Hence, the force generated by each of its four engines=300000 N

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
