I don't have the force (or acceleration or impulse) information needed. Tell me the net force as a function of time, the acceleration, or the impulse over the 4.0 s and I can compute it.
How to compute it:
- If you know the net force F(t): Δv = (1/m) ∫0^4 F(t) dt.
- If the net force is constant F: Δv = (F/m) · Δt = (F/m)·4.0 s.
- If you know acceleration a(t): Δv = ∫0^4 a(t) dt.
- If you know the impulse J (area under force–time curve): Δv = J / m.
Example: if F = 10.0 N constant on a 2.00 kg mass, Δv = (10.0/2.00)·4.0 = 20.0 m/s (rounded to 3 sig figs: 20.0 m/s).
Give me the force/acceleration/impulse and I’ll compute the numeric answer.
