Question

State Newton’s second law. Give mathematical formulation of Newton’s second law.

An object of mass 100 kg is accelerated uniformly from a velocity of 5 m/s to 8 m/s in 6

second. Calculate the initial and final momentum of the object. Also find the magnitude

of the force exerted on the object.

Answer 1

Answer:

Newton's Second Law in Terms of Momentum

Δp=Δ(mv). If the mass of the system is constant, then. Δ(mv)=mΔv. By substituting mΔv for Δp, Newton's second law of motion becomes. Fnet=ΔpΔt=mΔvΔt.
