If the velocity of a body changes from 13m/s to 30m/s while undergoing constant acceleration whats the average velocity of the body

The average velocity of the body is 21.5 m/s.

Step-by-step explanation:

Formula

As given

if the velocity of a body changes from 13m/s to 30m/s while undergoing constant acceleration.

Initial velocity = 13m/s

Final velocity = 30 m/s

Put in the above

Average velocity = 21.5 m/s

Therefore the average velocity of the body is 21.5 m/s.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
