Question

Average velocity has the formula______ *

(u + v)

(u + v + t) / 3

(u + v) / 2

​

Answer 1

Question :

Average velocity has the formula ___ *

a . u + v

b. ( u + v + t ) / 2

c. ( u + v ) / 2

d. None

Solution :

Average Velocity :

It is defined as ratio of total displacement and total time

$\bigstar\ \; \sf \pink{V_{Avg}=\dfrac{X_f-X_i}{T_f-T_i}}$

where ,

• X$\sf _f$ denotes final distance
• X$\sf _i$ denotes initial distance
• T$\sf _f$ denotes final time
• T$\sf _i$ denotes initial time

__________________________________________

If initial and final velocities are given , we can use the formula ,

$\bigstar\ \; \sf \green{V_{Avg}=\dfrac{u+v}{2}}$

where ,

• u denotes initial velocity
• v denotes final velocity

Option c [ ( u + v ) / 2 ]

Answer 2

Explanation:

Question :

Average velocity has the formula ___ *

a . u + v

b. ( u + v + t ) / 2

c. ( u + v ) / 2

d. None

Solution :

Average Velocity :

It is defined as ratio of total displacement and total time

\bigstar\ \; \sf \pink{V_{Avg}=\dfrac{X_f-X_i}{T_f-T_i}}★ V

Avg

=

T

f

−T

i

X

f

−X

i

where ,

X\sf _f

f

denotes final distance

X\sf _i

i

denotes initial distance

T\sf _f

f

denotes final time

T\sf _i

i

denotes initial time

__________________________________________

If initial and final velocities are given , we can use the formula ,

\bigstar\ \; \sf \green{V_{Avg}=\dfrac{u+v}{2}}★ V

Avg

=

2

u+v

where ,

u denotes initial velocity

v denotes final velocity

Option c [ ( u + v ) / 2 ]
