Question

Derive the unit of force using the second law of motion. A force of 5n produces an accleration of 8m/sec2 on a mass m , and an accleration of 24m/sec2 on mass m2. What accleration would the same force provide if both the masses are tied togeather

Answer 1

Answer:

According to newtons second law of motion "The rate of change of momentum is proportional to applied force and the change of momentum occurs in the direction of force"

It is the product of mass and velocity

it is denoted by P

.

. . P=MV

Suppose that initial momentum of an object is (mu),when a force is applied in the direction of its velocity for time (t),its velocity becomes (mv)

.

. . The rate of change of momentum =

change in momentum

-----------------------------------

Time

.

. . Rate of change of momentum =

mu-mv m(u-v)

------------ = ---------- =ma

t t

MA directly proportional to F

.

. . F= k MA

F= MA

NOW,force in both condition are same that is 5 N
