Find the work done in pumping gasoline that weighs 6600 newtons per cubic meter. a cylindrical gasoline tank 3 meters in diameter and 6 meters long is carried on the back of a truck and is used to fuel tractors. the axis of the tank is horizontal. the opening on the tractor tank is 5 meters above the top of the tank in the truck. find the work done in pumping the entire contents of the fuel tank into the tractor.

where is the circuit diagram ?

cant without the picture! ?

that would be because of both gravity and friction. so     c

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
