Question

Q4. How many cuboidal boxes can be formed of cuboid of measure 60m by 40m by 30m, if volume of each small cuboid box is 20m by 10m by 5m ? Please find this answer​

Answer 1

Answer:

Given:-

→ Initial velocity of the particle = 4m/s

→ Final velocity of the particle = 8m/s

→ Mass of the body = 2kg

→ Time taken = 2s

To find:-

→ Force needed by the body.

Solution:-

By Newton's 2nd law of motion , we know that :-

F = m(v - u)/t

Where :-

• F is the magnitude of force.

• m is mass of the body.

• v is final velocity of the body.

• u is initial velocity of the body.

• t is time taken.

By substituting values in the above equation, we get :-

=> F = 2(8 - 4)/2

=> F = 2(4)/2

=> F = 8/2

=> F = 4 N

Thus, the required amount of force

is 4 N .

Some Extra Information:-

• Force can be defined as a push or

a pull.

• Force is a vector quantity.

• S.I. unit of force is Newton(N). It's C.G.S.

unit is dyne.
