Displacement is simply the change in position, or the difference in the final and initial positions:

\Delta d = d_f - d_i

Then

(a) ∆<em>d</em> = 5 m - 0 m = 5 m

(b) ∆<em>d</em> = 1 m - (-2 m) = 1 m + 2 m = 3 m

(c) ∆<em>d</em> = 2 m - (-2 m) = 2 m + 2 m = 4 m

(d) ∆<em>d</em> = 6 m - 2 m = 4 m

A car with a mass of 3 Kg and velocity of 40 m/s collided with a truck of a velocity of 60 m/s, if the momentum is conserved wha
Luden [163]

Answer:

the mass of the truck is 2 kg.

Explanation:

Given;

mass of the car, m₁ = 3 kg

initial velocity of the car, u₁ = 40 m/s

initial velocity of the truck, u₂ = 60 m/s

let the mass of the truck = m₂

Apply the principle of conservation of linear momemtum;

m₁u₁ = m₂u₂

m₂ = (m₁u₁) / u₂

m₂ = (3 x 40) / (60)

m₂ = 2 kg

Therefore, the mass of the truck is 2 kg.
