Question

the force acting on a body when its Momentum changes by 10 kg
${ms}^{ - 1}$
in 5 second is how many newtons

Answer 1

we know that

IMPULSE = Force × time duration = change in momentum

therefore,
let the force me F

5F= 10 kg m/sec²
→ F=10/5=2 N

so, a 2N force is required to change the momentum of an object by 10 kg m/sec² in 5 seconds
