Consider two carts, of masses m and 2m, at rest on an air track. if you first push one cart for 3 s and then the other for the s
Marrrta [24]
F = m₁ a₁ = m₂ a₂

if m₁ = m and m₂ = 2m :

F = ma₁ = 2m  a₂ ⇒ a₁ = 2 a₂
 
since v = at + v₀  with t = 3, v₀ = 0 ⇒ v = 3a:

v₁ = 2 v₂

since p = vm with v₁ = 2v and v₂ = v :

p₁ = v₁m₁ = 2v ⁻ m
p₂ = v₂m₂ = v ⁻ 2m

p₁ = p₂

If the mass of an egg is 0.57kg and it is dropped, calculated the force using newton's 2nd law
nlexa [21]

F = ma

Acceleration in this case is acceleration due to gravity so

a = 9.8 m/s^2

and mass = 0.57kg

So..

F = (0.57)(9.8)

F = 5.586 or 5.56 N
