Answer:
Given : F=100 N m=2 kg t=10 s
Change in momentum of the body m(Δv)=F.t
where Δv is the change in velocity.
⟹ 2×Δv=100×10
⟹ Δv=500 m/s
Answer:
force= 100N
mass= 2kg
[tex]f = ma[/tex]
[tex]100 = 2 \times a[/tex]
[tex]a = \frac{100}{2} [/tex]
[tex]a = 50ms ^{ - 2} [/tex]
a=50 m/s² t= 10s
[tex]a = \frac{Δv}{Δt}[/tex]
[tex]50 = \frac{Δv} {10} [/tex]
[tex]Δv = 50 \times 10[/tex]
[tex]Δv = 500ms ^{ - 1} [/tex]
