The answer is +50Ns,
Impulse equals force (final time – initial time)
impulse = f * Δt
I = is a symbol for an impulse.
F = is a symbol for an object's force.
t = denotes the passage of time.
Due to the fact that the impulse is a measurement of how much the momentum alters as a result of a force acting on it over time. Derivation of Impulse: Impulse = p = p final - p initial .P refers to the momentum change.the final momentum is denoted by p final.the initial momentum is denoted by p initial .The formula's connection between impulse and an object's change in momentum is its most notable feature. Additionally, impulse can be measured in either kilogram meters per second (kg m/s) or Newton second.
