Question

An object A is moving with 5 ms-1 and B is moving with 10ms-1 in the same direction of positive X-axis simultaneously from the same point. Find the saparation between them after 10 sec

Answer 1

Answer :

Speed of object A = 5 m/s

Speed of object B = 10 m/s

We have to find distance between them after 10s$.$

★ In order to find separation between both objects after 10s, we have to find distance covered by each object in 10s.

Let A and B start their journey from origin.

We know that speed is defined as the ratio of distance travelled to the time taken.

• v = d / t

Distance covered by object A :

➠ d₁ = v₁ × t

➠ d₁ = 5 × 10

➠ d₁ = 50 m

Distance covered by object B :

➠ d₂ = v₂ × t

➠ d₂ = 10 × 10

➠ d₂ = 100 m

Separation between A and B :

➠ ∆d = d₂ - d₁

➠ ∆d = 100 - 50

➠ ∆d = 50 m

∴ Distance between object A and B after 10 s will be 50m.
