Question

find the force required to change the momentum of an object by 20 kg metre per second in 0.1 second​

Answer 1

Answer:

force of a body is the product of the mass of the body with the acceleration produced in the body.

FORMULA -----> F = m. a

momentum of the body is the product of the mass of the body with the velocity with which the body the body is moving.

FORMULA -----> P = m. v

so F = P / t

( which means that force is the rate of change of momentum in the given time)

so , change in momentum ( P ) = 10 kg m / s

Time taken = 0.01 s .

so Force applied ( F ) = ( 20 kg m/s ) / 0.01 s

= 2000 kg m /s ^2

or 2000 N .

Answer 2

Answer:

momentum/time gives you force....
